Believers! Do not draw near to the Prayer while you are intoxicated until you know what you are saying nor while you are defiled - save when you are travelling - until you have washed yourselves. If you are either ill or travelling or have satisfied a want of nature or have had contact with women and can find no water, then betake yourselves to pure earth, passing with it lightly over your face and your hands. Surely Allah is All-Relenting, All-Forgiving. 43 Have you not seen those who were given a portion of the Scripture, purchasing error [in exchange for it] and wishing you would lose the way? 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 Among those who are Jews, there are some who displace words from (their) right places and say: "We hear your word (O Muhammad SAW) and disobey," and "Hear and let you (O Muhammad SAW) hear nothing." And Ra'ina with a twist of their tongues and as a mockery of the religion (Islam). And if only they had said: "We hear and obey", and "Do make us understand," it would have been better for them, and more proper, but Allah has cursed them for their disbelief, so they believe not except a few. 46 O ye People of the Book! believe in what We have (now) revealed, confirming what was (already) with you, before We change the face and fame of some (of you) beyond all recognition, and turn them hindwards, or curse them as We cursed the Sabbath-breakers, for the decision of Allah Must be carried out. 47 God does not forgive that compeers be ascribed to Him, though He may forgive aught else if He please. And he who ascribes compeers to God is guilty of the gravest sin. 48 Have you not considered those who attribute purity to themselves? Nay, Allah purifies whom He pleases; and they shall not be wronged the husk of a date stone. 49 Look, how they invent a lie against Allah, and enough is that as a manifest sin. 50
