OxfordAQA IGCSE Islamiyat: Sources of Authority in Islam (9237)

This guide covers the textual core of Section 3.2.2 Sources of Authority in Islam — sub-topics 3.2.2.1 to 3.2.2.5 — from OxfordAQA International GCSE Islamiat (9237), Version 1.1, for International GCSE exams May/June 2026 onwards. It sits within Paper 2 alongside the study of the life of Hazrat Muhammad (peace be upon him).

Scope of this guide

Section 3.2.2 runs from 3.2.2.1 through to 3.2.2.9. This resource focuses on the five sub-topics that establish what the sources of authority actually are and how they work: the Qur’an’s revelation and compilation, its features and use, the Hadith and Sunnah as sources of Shariah, how Hadith is compiled and categorised, and the roles of Ijma and Qiyas. The remaining sub-topics — 3.2.2.6 to 3.2.2.9, covering how Shariah shapes everyday life and its personal, social and legal impact on a Muslim’s character — are left for a separate resource, since covering all nine sub-topics properly in one guide would not do justice to either the textual content here or the applied content there.

Syllabus coverage

OXFORDAQA INTERNATIONAL GCSE ISLAMIAT (9237) — SECTION 3.2.2: SOURCES OF AUTHORITY IN ISLAM

• 3.2.2.1 The revelation and compilation of the Qur’an — the significance of the Qur’an as the final revelation, including the way in which it was revealed, preserved, and compiled
• 3.2.2.2 The features and use of the Qur’an as a source of authority — the features of the Qur’an including the major themes of the Makki and Madni Surahs; the miraculous nature and infallibility of the Qur’an and the way in which it is used and treated
• 3.2.2.3 The Hadith and Sunnah as a source of Shariah — the relationship of the Hadith to the Qur’an as a source of guidance and Shariah law, including the importance of the teachings and Sunnah of Hazrat Muhammad (pbuh)
• 3.2.2.4 The compilation and categorisation of Hadith — the different categories of Hadith in relation to their reliability, including Sahih, Hasan, Daeef and Maudu; the methods used to test the reliability of Hadith including the Isnad (chains of transmission) and the Matn (text); the role of the main compilers of the major Hadith collections, including the main features of Sahih Bukhari and Sahih Muslim
• 3.2.2.5 Ijma and Qiyas as a source of Shariah — the meaning, role and importance of Ijma (consensus) and Qiyas (analogy) in forming religious rulings

The specification also requires students to study the prescribed passages linked to each part of this section, set out separately in the specification’s passages-for-study section.

How to approach it

The specification asks only for the meaning, role and importance of each source, and prescribes no fixed ranking among them — a common scholarly account treats the Qur’an as the primary, directly revealed source; the Hadith and Sunnah as recording the Prophet’s (pbuh) words and practice to explain and apply it; and Ijma and Qiyas as secondary sources scholars use to derive rulings where the Qur’an and Hadith do not give explicit guidance. Present this as a helpful scholarly account of how the sources relate, not as the one ordering an examination answer must give — the specification does not penalise a different, reasoned account of their relationship.

For 3.2.2.4, the Hadith categories (Sahih, Hasan, Daeef, Maudu) and the two-part reliability test (Isnad and Matn) are frequently tested together — know that Isnad checks the chain of narrators back to the Prophet (pbuh) while Matn checks the content of the text itself, since conflating the two is a common error.

Worked example: explaining why Hadith is needed alongside the Qur’an

A question asks candidates to explain the importance of Hadith as a source of authority in Islam.

Point:      The Qur'an provides general principles and commands but does
            not always explain how to put them into practice.
Evidence:   The Qur'an instructs Muslims to pray (Salah) and give
            charity (Zakah), but the Hadith and Sunnah record the exact
            method, timing and conditions the Prophet (pbuh)
            demonstrated for these acts of worship.
Explain:    Without the Hadith, many Qur'anic commands would remain
            open to interpretation, so the Hadith functions as the
            practical explanation of the Qur'an's guidance.
Link:       This is why the Hadith is described as the second source of
            Shariah, subordinate to but essential alongside the Qur'an.

This point-evidence-explain-link structure works for most “explain the importance of” questions across this section.

Common mistakes

Treating Ijma and Qiyas as equal in authority to the Qur’an and Hadith, rather than as secondary sources used only where the primary sources give no explicit ruling. Confusing Isnad (chain of narrators) with Matn (the text itself) when explaining how Hadith reliability is tested. Describing the Qur’an’s compilation without distinguishing revelation (how it was received), preservation (how it was memorised and recorded) and compilation (how it was assembled into a single text) as three distinct stages. Naming Sahih Bukhari and Sahih Muslim without being able to say anything about what makes them significant as collections.

Quick revision checklist

• Be able to place the Qur’an, Hadith/Sunnah, Ijma and Qiyas in order of authority and explain why.
• Learn the four Hadith reliability categories and the Isnad/Matn test.
• Separate the Qur’an’s revelation, preservation and compilation as distinct stages.
• Know one specific fact about Sahih Bukhari and Sahih Muslim each.
• Practise the point-evidence-explain-link structure for “importance of” questions.
