O you who believe, do not perform your service of prayer when you are intoxicated until you are sure of what you are saying, nor when in a state of seminal pollution, until you have taken a bath, except when you are travelling. But in case you are ill or are travelling, or you have relieved yourself of nature's call, or cohabited with a woman, and cannot find water, then take wholesome dust and pass it over your face and hands: God is benign and forgiving. 43 Have you not seen those who were given a portion of the Scripture, purchasing error [in exchange for it] and wishing you would lose the way? 44 And Allah is most knowing of your enemies; and sufficient is Allah as an ally, and sufficient is Allah as a helper. 45 Some among the Jews distort the words out of context and say (in place of the right words): "We have heard and do not obey;" and, "hear without hearing," and "listen to us," twisting their tongues and reviling the faith. But if they had said: "We have heard and obey," and, "hear and regard us," it would have been better for them and more appropriate. But God has disgraced them for their lack of belief; and so only a few of them believe. 46 O ye People of the Book! believe in what We have (now) revealed, confirming what was (already) with you, before We change the face and fame of some (of you) beyond all recognition, and turn them hindwards, or curse them as We cursed the Sabbath-breakers, for the decision of Allah Must be carried out. 47 Surely Allah does not forgive that anything should be associated with Him, and forgives what is besides that to whomsoever He pleases; and whoever associates anything with Allah, he devises indeed a great sin. 48 Hast thou not seen those who praise themselves for purity? Nay, Allah purifieth whom He will, and they will not be wronged even the hair upon a date-stone. 49 Look how they forge lies against Allah, and it is sufficient for a clear sin. 50
