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 Observest thou not those unto whom was vouchsafed a portion of the book purchasing error, and desiring that ye would err as regards the way! 44 Allah knoweth best (who are) your enemies. Allah is sufficient as a Guardian, and Allah is sufficient as a Supporter. 45 Some Jews take words out of their context and say, "We have heard, but we disobey," or "Hear without listening." And they say "Look at us," twisting the phrase with their tongues so as to disparage religion. But if they had said, "We hear and we obey," and "Listen to us and look at us with favour," that would have been better and more proper for them. God has rejected them for their defiance so that they shall not believe, except a few of them. 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 God does not forgive the sin of considering others equal to Him, but He may choose to forgive other sins. Whoever believes in other gods besides Him has indulged in a great sin. 48 Hast thou not observed those who hold themselves purified? Nay! Allah purifieth whomsoever He will, and they shall not be wronged a whit. 49 Behold! how they invent a lie against Allah! but that by itself is a manifest sin! 50
