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 to whom a portion of the Book was given? They purchased error for themselves, and wish that you too lose the right way? 44 God knows well your enemies; God suffices as a protector, God suffices as a helper. 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 You who have been given the Book, believe in what We have sent down, confirming what is with you, before We obliterate faces, and turn them upon their backs, or curse them as We cursed the Sabbath-men, and God's command is done. 47 Lo! Allah forgiveth not that a partner should be ascribed unto Him. He forgiveth (all) save that to whom He will. Whoso ascribeth partners to Allah, he hath indeed invented a tremendous sin. 48 Have you not seen those who claim themselves to be pure? Rather, Allah purifies whom He wills, and injustice is not done to them, [even] as much as a thread [inside a date seed]. 49 Look how they forge lies against Allah, and it is sufficient for a clear sin. 50
