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 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 But God knows your enemies well: and sufficient is God to protect you, and sufficient is God for all help. 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 People of the Book, have faith in the Quran that We have revealed to confirm your Book, before certain faces are changed and turned back. We shall condemn them as We did the people of the Sabbath about whom God's decree had decisively been ordained. 47 Verily, Allah forgives not that partners should be set up with him in worship, but He forgives except that (anything else) to whom He pleases, and whoever sets up partners with Allah in worship, he has indeed invented a tremendous 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 Behold how they fabricate a lie against Allah! and sufficeth that as a manifest sin. 50
