The scholars agreed that ablution is one of the conditions of prayer, but they differed as to whether it is a condition of validity or a condition of obligation. By ablution, I mean legitimate purity, which in our view is an obligatory condition. Purity in our view is an independent act of worship, and it may be a condition in other worship, a condition of validity or a condition of obligation, and it may be desirable and Sunnah in other worship.
