O ye who believe! Approach not prayers with a mind befogged, until ye can understand all that ye say,- nor in a state of ceremonial impurity (Except when travelling on the road), until after washing your whole body. If ye are ill, or on a journey, or one of you cometh from offices of nature, or ye have been in contact with women, and ye find no water, then take for yourselves clean sand or earth, and rub therewith your faces and hands. For Allah doth blot out sins and forgive again and again. 43 Do you not know of those who were in possession of a portion of the Book? They buy up error and want you to lose your way. 44 God knows who are your enemies. You need to have no guardian or helper other than God. 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 Allah does not forgive (the sin of inventing an) association with Him, but He forgives other (sins) to whomsoever He will. He who associates with Allah has invented a great sin. 48 Have you not seen those who consider themselves pure? It is indeed God who purifies whoever He pleases and none shall be wronged by as much as a hair's breadth. 49 Look how they forge lies against Allah, and it is sufficient for a clear sin. 50
