Farḍ (Arabic: فرض) or farīḍah (فريضة) in Islam is a religious duty commanded by God. The word is also used in Persian, Pashto, Turkish (spelled farz) in the same meaning. Muslims who obey such commands or duties are said to receive hasanat, ajr or thwab each time for each good deed.
Fard or its synonym wājib (واجب) is one of the five types of ahkam into which fiqh categorizes acts of every Muslim. The Hanafi fiqh, however, makes a distinction between wajib and fard, the latter being obligatory and the former merely necessary.
