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 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 Allah has full knowledge of your enemies, and Allah is Sufficient as a Wali (Protector), and Allah is Sufficient as a Helper. 45 Among those of the Jewish faith there are some who distort the meaning of the [revealed] words, taking them out of their context and saying, [as it were,] "We have heard, but we disobey," and "Hear without hearkening," and "Hearken thou unto us, (O Muhammad)" - thus making a play with their tongues, and implying that the [true] Faith is false. And had they but said, "We have heard, and we pay heed," and "Hear [us,] and have patience with us," it would indeed have been for their own good, and more upright: but God has rejected them because of their refusal to acknowledge the truth - for it is in but few things that they believe. 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 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 Behold how they fabricate a lie against Allah! and sufficeth that as a manifest sin. 50
