Fiqh and Usul al-Fiqh
What this domain tests
Fiqh and usul test applied worship rulings and the principles behind them, mainly within the Shafi'i school taught in Malaysia. You need to know the evidence, the hukm, and the reason, not just a final answer.
Core rules
- Primary sources: Quran, Sunnah, ijma', qiyas. Supporting principles include istishab, masalih mursalah, and 'urf.
- Ahkam taklifi: wajib, mandub, haram, makruh, mubah. Ahkam wad'i: sabab, shart, mani'.
- Qawa'id: al-yaqin la yazul bi al-shakk (certainty is not removed by doubt); al-mashaqqah tajlib al-taysir (hardship brings ease); la darar wa la dirar (no harm and no reciprocating harm).
- Usul terms: amr (command), nahy (prohibition), 'amm (general), khas (specific), mutlaq, muqayyad.
Worked example
After completing wudu, a person feels a slight sensation but hears no sound and smells nothing. Reasoning: the certainty is that wudu remains; the doubt is whether it broke. Applying al-yaqin la yazul bi al-shakk, the wudu stands. The hadith instructs not to leave the prayer until one hears a sound or smells an odour, which supports the same principle. Saying I will repeat wudu to be safe may be praiseworthy in some contexts, but it is not required by this evidence and can suggest waswas.
Traps
- Mixing fard and sunnah, then calling a missed sunnah an invalidating omission.
- Using qiyas without identifying the effective cause ('illah).
- Applying a ruling from another madhhab without noting the difference.
- Treating makruh as haram or mubah as rewardable.
- Ignoring a clear hadith because of a local custom.
