O Ye who believe! approach not prayer while ye are intoxicated until ye know that which ye say, nor yet while ye are polluted, save when ye be way faring, until ye have washed yourselves. And if ye be ailing or on a journey, or one of you cometh from the privy or ye have touched women, and ye find not water, then betake your selves to clean earth and wipe your faces and your hands therewith; verily Allah is ever Pardoning, Forgiving. 43 Hast thou not regarded those who were given a share of the Book purchasing error, and desiring that you should also err from the way? 44 Allah has full knowledge of your enemies, and Allah is Sufficient as a Wali (Protector), and Allah is Sufficient as a Helper. 45 Some Jews tampered with the words (altering) their places saying: 'We have heard and we disobey' and 'Hear, without hearing' and 'Observe us (Ra'ina, in Hebrew means evil)', twisting with their tongues traducing religion. But 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 Allah has cursed them for their disbelief, so they do not believe, except a few. 46 O people of the Book, believe in what We have revealed, which confirms what is already with you before We disfigure your visages and turn your faces about and curse you, as We did with those who had broken the Sabbath; and what God decrees comes to pass. 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 Look how they forge lies against Allah, and it is sufficient for a clear sin. 50
