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 Have you not seen the people who were given a share of the Book, but who purchased only error, and wish that you also go astray? 44 And Allah is most knowing of your enemies; and sufficient is Allah as an ally, and sufficient is Allah as a helper. 45 Some of the Jews pervert words from their meanings saying, 'We have heard and we disobey' and 'Hear, and be thou not given to hear' and 'Observe us,' twisting with their tongues and traducing religion. If they had said, 'We have heard and obey' and 'Hear' and 'Regard us,' it would have been better for them, and more upright; but God has cursed them for their unbelief so they believe not except a few. 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 Surely Allah does not forgive that anything should be associated with Him, and forgives what is besides that to whomsoever He pleases; and whoever associates anything with Allah, he devises indeed 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 See how they forge the lie against Allah, and this is sufficient as a manifest sin. 50
