Fiqh (Islamic Jurisprudence)

Fiqh literally means "deep understanding" and refers to Islamic jurisprudence — the systematic derivation of practical rules from the Quran, the Sunnah, ijma' (consensus), and qiyas (analogy). Fiqh covers all aspects of Muslim life, from worship ('ibadat) to social relations (mu'amalat).

Prayer rules (fiqh al-salah) constitute one of the most detailed parts of fiqh. They cover the prayer's conditions (shurut), pillars (arkan), obligations (wajibat), sunnah acts, and invalidating factors (mubtilat). Each school of law has its own detailed set of rules based on their interpretation of the sources.

Imam Abu Hanifah said: "Fiqh is knowing the soul's rights and obligations." Al-Shafi'i defined fiqh as "knowledge of the practical shariah rules derived from their detailed evidence." The great fiqh works such as al-Hidayah (Hanafi), al-Mudawwanah (Maliki), al-Umm (Shafi'i), and al-Mughni (Hanbali) are still studied today as foundational texts in Islamic jurisprudence.
