O ye who believe! Draw not near unto prayer when ye are drunken, till ye know that which ye utter, nor when ye are polluted, save when journeying upon the road, till ye have bathed. And if ye be ill, or on a journey, or one of you cometh from the closet, or ye have touched women, and ye find not water, then go to high clean soil and rub your faces and your hands (therewith). Lo! Allah is Benign, Forgiving. 43 Have you not seen those to whom a portion of the Book was given? They purchased error for themselves, and wish that you too lose the right way? 44 And Allah best knows your enemies; and Allah suffices as a Guardian, and Allah suffices 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 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 God does not forgive the sin of considering others equal to Him, but He may choose to forgive other sins. Whoever believes in other gods besides Him has indulged in a great sin. 48 Have you not seen those who claim themselves to be pure? Rather, Allah purifies whom He wills, and injustice is not done to them, [even] as much as a thread [inside a date seed]. 49 See how they fabricate lies against Allah! And this is a sufficient manifest sin. 50
