Introduction
There is a moment that every sincere Islamic school teacher encounters — a moment when the technical work of teaching Tajweed or marking Hifz registers gives way to a different and harder question: what am I actually trying to produce? Not which Juz’ the student is on, not whether they passed their term assessment, but who this child is becoming, and what my role in that becoming actually is.
Imam Abu Hamid Al-Ghazali (1058–1111 CE) spent his life answering that question. The greatest Islamic scholar of his era — and arguably of the post-Companion period — he abandoned a prestigious professorship in Baghdad at the height of his fame because he recognised that his own education had given him extensive knowledge without genuine spiritual transformation. He spent a decade wandering, learning, and reflecting — and then wrote Ihya Ulum al-Din (The Revival of the Religious Sciences), one of the most comprehensive and influential works in Islamic intellectual history.
Within the Ihya, Al-Ghazali’s treatment of knowledge and education — the Kitab al-Ilm (Book of Knowledge) — contains a philosophy of teaching and learning that is as practical and as demanding as it was nine centuries ago. This article extracts that philosophy and applies it to the concrete work of running an Islamic school.
Who Was Imam Al-Ghazali?
Abu Hamid Muhammad ibn Muhammad al-Ghazali was born in Tus, Khorasan (modern Iran) in 1058 CE. He demonstrated exceptional scholarly ability from childhood and was eventually appointed to the prestigious Nizamiyya college in Baghdad — the foremost academic institution of the Islamic world — at the age of 33. He was at this point one of the most celebrated scholars in the Muslim world, drawing hundreds of students to his lectures.
Then, in 1095, he stopped. He later described a spiritual crisis — a realisation that he had accumulated knowledge for the sake of reputation and worldly recognition rather than for the sake of Allah, and that this orientation had made his knowledge hollow. He resigned, left Baghdad, and spent approximately ten years in a combination of spiritual retreat, pilgrimage, and wandering through Syria, Palestine, and the Hejaz.
During this period — and in the years following — he wrote Ihya Ulum al-Din, a 40-volume work designed to revive Islamic religious life by reconnecting its external observances to their internal spiritual substance. The work covers prayer, fasting, knowledge, character, social conduct, and the spiritual path — and it remains one of the most widely read works in the Islamic world.
The Kitab al-Ilm (Book of Knowledge), the second book in the Ihya, is Al-Ghazali’s direct treatment of education. It is simultaneously a manual for students and teachers, a critique of the educational culture of his era, and a theological argument for why knowledge matters — and why most knowledge transmission fails.
The Kitab al-Ilm — Al-Ghazali’s Book of Knowledge
The Kitab al-Ilm opens with the famous hadith: “Seeking knowledge is an obligation upon every Muslim” — and then immediately asks the question that the hadith demands: what kind of knowledge? Al-Ghazali’s answer structures the entire work: the knowledge that is obligatory is the knowledge that guides a Muslim toward Allah and away from what displeases Him. All other knowledge — however impressive — is secondary.
This seemingly simple answer has radical implications for Islamic school curriculum design. If the purpose of knowledge is nearness to Allah, then an Islamic school whose graduates know the rules of Tajweed but have not developed the qualities that bring them closer to Allah has failed — even if their examination results are excellent.
On the Purpose of Knowledge — Ilm as Ibadah
Al-Ghazali insists that knowledge (Ilm) is not merely a means to other ends — it is itself an act of worship (Ibadah), when pursued with the correct intention. A student who studies the Quran to gain the pleasure of Allah and to draw closer to Him is performing an act of worship equal in merit to voluntary prayer. A student who studies the Quran to impress their parents, compete with peers, or gain social recognition is doing something else entirely — and may, Al-Ghazali warns, be accumulating sins rather than rewards.
For teachers and administrators, this has a direct implication: the first lesson in any Islamic school should not be Tajweed rules or Qaidah letters. The first lesson should be why — the intention (Niyyah) that will make everything that follows meaningful.
Al-Ghazali’s hierarchy of knowledge purpose:
| Purpose | Status |
| Knowledge for nearness to Allah | Highest — this is knowledge as Ibadah |
| Knowledge for the benefit of the Muslim community | High — this is a collective duty |
| Knowledge for the refinement of the self | Good — Tarbiyah in action |
| Knowledge for worldly benefit (employment, status) while maintaining Islamic values | Permissible but lower |
| Knowledge for reputation, competition, or self-glorification | Dangerous — may corrupt the knower |
The Etiquette of the Student — Ten Duties
Al-Ghazali outlines ten duties of the student in the Kitab al-Ilm. Each is a Tarbiyah principle with direct classroom application:
| Duty | Al-Ghazali’s Principle | Application in a Maktab |
| 1 | Purify the inner self before seeking knowledge | Begin each session with the correct intention — not to perform, but to learn for Allah’s sake |
| 2 | Reduce worldly attachment that distracts from learning | Students who are distracted by entertainment cannot be present for Hifz — this is a home environment conversation |
| 3 | Maintain humility before the teacher and not argue prematurely | Students should receive correction without defensiveness — this is Adab, and it must be taught |
| 4 | Avoid premature disagreement with different scholarly opinions | Advanced students who encounter differing opinions should listen before critiquing |
| 5 | Know which knowledge to prioritise | The student who wants to learn everything at once learns nothing deeply — sequence matters |
| 6 | Not advance to a new subject before mastering the current one | The equivalent of the Maqbul requirement before advancing in Hifz |
| 7 | Not pursue multiple texts simultaneously before mastering one | Curriculum focus: do not introduce too many subjects at once in the early years |
| 8 | Understand the connection between subjects | Knowledge is unified — Tajweed serves Hifz; Hifz serves Salah; Salah serves Taqwa |
| 9 | Know the goal of each subject and pursue it sincerely | Why is this student learning Tajweed? They should be able to answer this |
| 10 | Know one’s purpose and subordinate all knowledge to it | The formation of a Muslim who lives by what they know — Tarbiyah as the ultimate goal |
The Etiquette of the Teacher — Ten Duties
Al-Ghazali’s ten duties of the teacher are among the most frequently cited passages in Islamic educational thought — and among the most frequently violated in Islamic educational practice:
| Duty | Al-Ghazali’s Principle | What It Looks Like in Practice |
| 1 | Show compassion to students and treat them as your own children | The teacher who cares about students as people, not as performance metrics |
| 2 | Follow the example of the Prophet ﷺ — seek no reward except the reward of Allah | Teaching as a vocation, not merely employment |
| 3 | Never withhold good advice from a student | Honest feedback, even when uncomfortable — not false praise to avoid conflict |
| 4 | Discourage a student from certain sciences using hints before explicit prohibition | Wise guidance: redirect before confronting |
| 5 | Do not speak ill of other sciences to a student — let them make their own assessments | Teachers who denigrate other Islamic approaches are damaging their students’ broader learning |
| 6 | Confine instruction to the student’s level of understanding | The teacher who pitches above the student’s level is not teaching — they are performing |
| 7 | Address the dull student with clarity and not belittle the capable one | Differentiated teaching is an Islamic obligation, not a modern pedagogical innovation |
| 8 | Apply knowledge in one’s own life — not contradict it in action | The teacher whose conduct contradicts their teaching has undermined their authority |
| 9 | Do not be jealous of students who surpass the teacher | The mark of a great teacher: they produce students better than themselves |
| 10 | Know the limits of one’s knowledge and say “I do not know” when necessary | Intellectual honesty — the teacher who pretends to know everything teaches students to do the same |
The Hierarchy of Knowledge — What Should Be Taught First?
Al-Ghazali divides knowledge into obligatory (Fard ‘Ayn) and communally obligatory (Fard Kifayah). The Fard ‘Ayn knowledge — what every Muslim must know — takes clear precedence in any Islamic school curriculum:
| Category | Content | Priority |
| Fard ‘Ayn | Knowledge required for valid practice of Islam: sufficient Quran recitation, basic Fiqh (prayer, fasting, purity), core Aqeedah | Highest — this is the irreducible minimum for every student |
| Fard Kifayah — Religious | Advanced Islamic sciences: Fiqh, Tafsir, Hadith, Arabic grammar | High — required for the community as a whole |
| Fard Kifayah — Worldly | Mathematics, medicine, engineering — sciences the community needs | Important but secondary to religious knowledge |
| Praiseworthy non-obligatory | Literature, history, sciences that benefit civilisation | Valuable when the above are fulfilled |
| Blameworthy | Knowledge that harms: dark arts, content that corrupts | Forbidden |
For a maktab curriculum, this hierarchy provides clear guidance: ensure every student’s Fard ‘Ayn knowledge is complete before pursuing anything else. A student who has not learned to pray correctly has not yet received the most basic entitlement of Islamic education.
On the Dangers of Knowledge Without Action
One of Al-Ghazali’s most distinctive and sobering insights is that knowledge which is not translated into action — Ilm that does not produce Amal — can be more dangerous than ignorance. The scholar who knows the rules of Islamic conduct but does not live by them is, in Al-Ghazali’s framework, in greater spiritual danger than an ignorant person — because they have been given a trust and have not fulfilled it.
He uses a vivid analogy: a person who knows the path to a destination but does not travel it is in a worse position than someone who does not know the path, because the knowledgeable person’s lack of action is a deliberate choice, not an accident of ignorance.
For Islamic schools, this principle challenges the reduction of Islamic education to examination performance. A student who can recite the hadith on good character and receives full marks on the relevant examination — but whose conduct outside the exam room is dishonest, rude, and self-serving — has not received an Islamic education. They have received Islamic information.
Al-Ghazali on the Flawed Teacher
Al-Ghazali is explicit and specific about teachers who damage rather than develop their students. His targets include:
The scholar who teaches for fame. A teacher whose primary motivation is the admiration of students — who performs learning rather than transmitting it — communicates this to students. Students learn from the teacher’s orientation as much as from their words. If the teacher values reputation, students learn to value reputation.
The scholar whose conduct contradicts their teaching. Al-Ghazali considers this among the greatest spiritual dangers in the educational sphere. A Hifz teacher who memorises the Quran but treats their spouse, students, or colleagues with disrespect is, in Al-Ghazali’s framework, engaged in an active contradiction that teaches students that the Quran’s moral content is separable from its recitation — which is exactly the opposite of what Islamic education intends.
The scholar who competes with other scholars. Intellectual jealousy — scholars or teachers who diminish their colleagues to elevate themselves — is, for Al-Ghazali, a sign that knowledge has corrupted rather than purified its holder.
These failures are recognisable in Islamic educational institutions of every era — and every era has produced Al-Ghazali’s warning about them without necessarily heeding it.
Eight Lessons for Islamic School Administrators
Lesson 1: Begin with intention. Before teaching Tajweed rules, teach students why they are learning them. The Niyyah that motivates learning determines its spiritual value and its durability.
Lesson 2: The teacher’s character is the curriculum. Al-Ghazali’s ten duties of the teacher make one thing unmistakable: who the teacher is matters more than what the teacher knows. Teacher selection and teacher development are Tarbiyah decisions.
Lesson 3: Compassion is not sentimentality — it is pedagogy. A teacher who treats students with the compassion Al-Ghazali describes creates an environment where genuine learning happens. This is not in tension with high standards; it is the condition for meeting them.
Lesson 4: Assess whether knowledge is becoming action. Design your school’s evaluation to look for evidence of Amal — conduct, character, practice — alongside academic knowledge. The student who knows the rules of Salah and prays consistently is a better outcome than the student who knows the rules and does not pray.
Lesson 5: Confine instruction to the student’s level. This is not about low expectations — it is about effective sequencing. Teaching above the student’s capacity produces the appearance of learning, not the substance.
Lesson 6: Prioritise Fard ‘Ayn before everything else. Every student must leave your school able to pray correctly, recite the Quran sufficiently, and hold the core beliefs of Islam. Everything else — however valuable — is secondary.
Lesson 7: Say “I do not know” when you do not know. This simple practice — modelling intellectual honesty for students — is one of the most powerful pedagogical acts a teacher can perform. A teacher who never says “I don’t know” teaches students that the appearance of knowledge matters more than its reality.
Lesson 8: The goal is a Muslim who lives by what they know. Everything in the school — the timetable, the curriculum, the assessment, the teacher-student relationship — is a means to this end. When any element of the school begins to serve itself rather than this end, it has become an obstacle.

Conclusion
Al-Ghazali’s challenge to Islamic education is as direct in 2026 as it was in 1095. He is not asking Islamic schools to lower their academic standards or reduce their Hifz targets. He is asking them to ask a harder question: is this school producing Muslims who draw closer to Allah through what they have learned? Or is it producing graduates who can pass Islamic examinations without Islamic transformation? The answer to that question determines whether an Islamic school is doing what it was built to do — or whether, in Al-Ghazali’s terms, it is reviving the sciences or merely their appearances.
