O believers, draw not near to prayer when you are drunken until you know what you are saying, or defiled -- unless you are traversing a way -- until you have washed yourselves; but if you are sick, or on a journey, or if any of you comes from the privy, or you have touched women, and you can find no water, then have recourse to wholesome dust and wipe your faces and your hands; God is All-pardoning, All-forgiving. 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 But Allah hath full knowledge of your enemies: Allah is enough for a protector, and Allah is enough for 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 People of the Book, believe in what We have sent down, fulfilling [the predictions] that is with you, before We destroy [your sense of] direction, so as to confound or reject you, as We rejected those who broke the Sabbath: God's command is always 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 the people who call themselves pure? Yet God purifies whom He pleases, and none shall be wronged even the breadth of a thread. 49 Behold how they attribute their own lying inventions to God - than which there is no sin more obvious. 50
