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 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 And Allah is most knowing of your enemies; and sufficient is Allah as an ally, and sufficient is Allah as a helper. 45 Among the Jews are those who distort words from their [proper] usages and say, "We hear and disobey" and "Hear but be not heard" and "Ra'ina," twisting their tongues and defaming the religion. And if they had said [instead], "We hear and obey" and "Wait for us [to understand]," it would have been better for them and more suitable. But Allah has cursed them for their disbelief, so they believe not, except for a few. 46 O you who have been given the Scripture (Jews and Christians)! Believe in what We have revealed (to Muhammad SAW) confirming what is (already) with you, before We efface faces (by making them like the back of necks; without nose, mouth, eyes, etc.) and turn them hindwards, or curse them as We cursed the Sabbath-breakers. And the Commandment of Allah is always executed. 47 Lo! Allah forgiveth not that a partner should be ascribed unto Him. He forgiveth (all) save that to whom He will. Whoso ascribeth partners to Allah, he hath indeed invented a tremendous sin. 48 Have you not seen those who boast of their righteousness, even though it is Allah Who grants righteousness to whomsoever He wills? They are not wronged even as much as the husk of a date-stone (if they do not receive righteousness). 49 See how they fabricate lies against Allah! And this is a sufficient manifest sin. 50
