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 the people who were given a share of the Book, but who purchased only error, and wish that you also go astray? 44 And Allah is most knowing of your enemies; and sufficient is Allah as an ally, and sufficient is Allah as a helper. 45 Some Jews take words out of their context and say, "We have heard, but we disobey," or "Hear without listening." And they say "Look at us," twisting the phrase with their tongues so as to disparage religion. But if they had said, "We hear and we obey," and "Listen to us and look at us with favour," that would have been better and more proper for them. God has rejected them for their defiance so that they shall not believe, except a few of them. 46 O you who have been granted the Book! Do believe in what We have (now) revealed, which confirms the revelation which you already possess. Do this before We alter countenances, turning them backwards, or lay a curse upon them as We cursed the Sabbath-men. Bear in mind that Allah's command is done. 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 seen those who exalt themselves? Rather, Allah purifies whom He will and they shall not be wronged a single tissue that covers a date stone. 49 Look, how they invent a lie against Allah, and enough is that as a manifest sin. 50
