OxfordAQA IGCSE Islamiyat: Sources of Authority in Islam — Revision Notes

Condensed for the final weeks. For the full explanation, use the Sources of Authority in Islam study guide.

The hierarchy, fixed in order

Learn the four sources as an ordered hierarchy, not a flat list — most exam questions on this section reward being able to explain why one source outranks another:

1. Qur’an — the primary, directly revealed source.
2. Hadith and Sunnah — record the Prophet’s (pbuh) words and practice, explaining and applying the Qur’an’s guidance in practice.
3. Ijma (consensus) and Qiyas (analogy) — secondary sources scholars use only where the Qur’an and Hadith give no explicit ruling.

Why this order matters for exam answers: a question that asks “why is the Hadith needed alongside the Qur’an” is really asking you to explain position 2’s role relative to position 1 — the Qur’an gives commands, but Hadith supplies the practical detail of how to carry them out.

The Qur’an: three separate stages

Do not blur these together — they are frequently tested as distinct steps:

Stage	What it means
Revelation	How the Qur’an was received
Preservation	How it was memorised and recorded
Compilation	How it was assembled into a single text

A strong answer names which of the three stages a question is actually asking about, rather than describing the Qur’an’s history as one undifferentiated process.

Hadith reliability: two tests, not one

The four Hadith categories — Sahih (sound), Hasan (good), Daeef (weak), Maudu (fabricated) — are assessed using two separate checks:

• Isnad — the chain of narrators transmitting the Hadith back to the Prophet (pbuh).
• Matn — the actual text/content of the Hadith itself.

Common confusion to avoid: Isnad and Matn test different things — a Hadith can have a strong chain of narrators (Isnad) but still raise questions about its content (Matn), or vice versa. Conflating the two into one generic “reliability check” loses marks.

Ijma and Qiyas — know one example mechanism each

• Ijma (consensus) — scholars agree on a ruling where the Qur’an and Hadith are silent.
• Qiyas (analogy) — a new situation is reasoned about by comparison to a similar situation already addressed in the Qur’an or Hadith.

Both exist specifically to extend guidance to situations the primary sources do not explicitly cover — state this purpose explicitly rather than just naming the two terms.

The point-evidence-explain-link structure

For “explain the importance of ___” questions (a recurring format in this section), use:

1. Point — state the claim.
2. Evidence — a specific example (e.g. Salah or Zakah as Qur’anic commands).
3. Explain — how the Hadith supplies the practical detail the Qur’an does not.
4. Link — back to the source’s position in the hierarchy.

Sahih Bukhari and Sahih Muslim — one fact each

Do not name these two major Hadith collections without being able to say something specific about their significance as compilations — a bare name-drop earns little on its own; a factual point about what makes each collection significant does.

The nine sub-topics, and where this resource sits

Section 3.2.2 Sources of Authority runs from 3.2.2.1 through to 3.2.2.9. These notes cover the first five sub-topics — the ones establishing what the sources are and how they work. The remaining sub-topics (3.2.2.6 to 3.2.2.9) cover how Shariah shapes everyday personal, social and legal life, and are revised separately. Knowing where these notes’ scope ends matters: a question drawing on the later sub-topics needs different preparation from the hierarchy-and- reliability content covered here.

Exam traps

• Treating Ijma and Qiyas as equal in authority to the Qur’an and Hadith, rather than as secondary, situation-filling sources.
• Confusing Isnad (chain of narrators) with Matn (the text itself).
• Describing the Qur’an’s history as one process rather than three distinct stages (revelation, preservation, compilation).
• Naming Sahih Bukhari or Sahih Muslim with no further detail.
• Skipping the “link back to the hierarchy” step in an “explain the importance” answer.

Prescribed passages — do not overlook them

The specification requires students to study prescribed passages linked to each part of this section, set out separately in its own passages-for-study list. Revision that covers only the conceptual content above (the hierarchy, the reliability tests, Ijma and Qiyas) without also reviewing the specific prescribed passages risks being unable to answer a question that asks directly about one of them — treat the passages-for-study list as a mandatory companion to these notes, not an optional extra.

Self-test

1. Place the four sources of authority in order and explain why Ijma and Qiyas sit below the Qur’an and Hadith.
2. Name the Qur’an’s three distinct historical stages.
3. What do Isnad and Matn each test?
4. Name the four Hadith reliability categories.
5. What is the point-evidence-explain-link structure used for?

Answers: 1. Qur’an, then Hadith/Sunnah, then Ijma and Qiyas; Ijma and Qiyas are secondary sources used by scholars only where the Qur’an and Hadith give no explicit ruling, so they rank below both. 2. Revelation, preservation, compilation. 3. Isnad tests the chain of narrators transmitting a Hadith back to the Prophet (pbuh); Matn tests the content of the Hadith text itself. 4. Sahih, Hasan, Daeef, Maudu. 5. Answering “explain the importance of ___” questions: state the point, give specific evidence, explain the mechanism, then link back to the source’s position in the hierarchy of authority.
