Lit. “Demanding.” A term used in the exegesis of the Qur’an for sentence which demand certain conditions, e.g. Surah iv. 94: “Whoso killeth a Mu’min (a believer) by mischance shall be bound to free a slave.” Here the condition demanded is that the slave shall be the property of the person who frees him, and if he have not a slave to free, then some other expiation is required.
