O YOU who have attained to faith! Do not attempt to pray while you are in a state of drunkenness, [but wait] until you know what you are saying; nor yet [while you are] in a state requiring total ablution, until you have bathed - except if you are travelling [and are unable to do so]. But if you are ill, or are travelling, or have just satisfied a want of nature, or have cohabited with a woman, and can find no water - then take resort to pure dust, passing [therewith] lightly over your face and your hands. Behold, God is indeed an absolver of sins, much-forgiving. 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 Allah knoweth best (who are) your enemies. Allah is sufficient as a Guardian, and Allah is sufficient as a Supporter. 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 you who were given the Scripture, believe in what We have sent down [to Muhammad], confirming that which is with you, before We obliterate faces and turn them toward their backs or curse them as We cursed the sabbath-breakers. And ever is the decree of Allah accomplished. 47 God forgives not that aught should be with Him associated; less than that He forgives to whomsoever He will. Whoso associates with God anything, has indeed forged a mighty sin. 48 Hast thou not observed those who hold themselves purified? Nay! Allah purifieth whomsoever He will, and they shall not be wronged a whit. 49 Behold how they attribute their own lying inventions to God - than which there is no sin more obvious. 50
