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 Have you seen those who had received a portion of the Book trade misguidance and try to make you, too, go astray? 44 But God knows best who are your enemies: and none can befriend as God does, and none can give succour as God does. 45 Some of those who are Jews change words from their context and say: "We hear and disobey; hear thou as one who heareth not" and "Listen to us!" distorting with their tongues and slandering religion. If they had said: "We hear and we obey: hear thou, and look at us" it had been better for them, and more upright. But Allah hath cursed them for their disbelief, so they believe not, save a few. 46 O People of the Book, believe in what We have sent down, fulfilling [the predictions] that is with you, before We destroy [your sense of] direction, so as to confound or reject you, as We rejected those who broke the Sabbath: God's command is always carried out. 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 Hast thou not seen those who praise themselves for purity? Nay, Allah purifieth whom He will, and they will not be wronged even the hair upon a date-stone. 49 See how they fabricate lies against Allah! And this is a sufficient manifest sin. 50
