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 Did you not see those who received a portion of the Book, that they purchase error and wish that you too go astray from the right path? 44 God knows well your enemies; God suffices as a protector, God 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 O Ye who are vouchsafed the Book believe in that which We have sent down confirming that which is with you, ere We alter countenances and turn them into their hinder parts, or We might curse them even as We cursed the fellows of the Sabt; and Allah's command is ever fulfilled. 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 (Muhammad), have you seen those who try to purify themselves? They should know that God only purifies whomever He wants and that the slightest wrong will not be done to such people. 49 Behold! how they invent a lie against Allah! but that by itself is a manifest sin! 50
