I'lam al-Muwaqqi'in

إعلام الموقعين عن رب العالمين

A masterwork on the philosophy and methodology of Islamic legal reasoning. Ibn al-Qayyim discusses the qualifications of a mufti, the relationship between text and reason, the wisdom behind Islamic rulings, and the principles of juristic analogy and legal stratagems. The work is both a manual of usul al-fiqh and a passionate defense of deriving rulings from evidence rather than blind imitation (taqlid).
