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 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 And Allah is most knowing of your enemies; and sufficient is Allah as an ally, and sufficient is Allah as a helper. 45 Of those who are Judaised, are they who pervert words from their meanings and say: We hear and we disobey, and: hear thou without being made to hear, and RA'INA, twisting their tongues and scoffing at the faith! And had they said: we hear and obey, and: hear thou, and: UNZURNA, it had surely been better for them and more upright. But Allah hath cursed them for their infidelity, wherefore they shall not believe, save a few. 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 Allah forgiveth not that partners should be set up with Him; but He forgiveth anything else, to whom He pleaseth; to set up partners with Allah is to devise a sin Most heinous indeed. 48 Have you not seen those who claim themselves to be pure? Rather, Allah purifies whom He wills, and injustice is not done to them, [even] as much as a thread [inside a date seed]. 49 See how they fabricate lies about God, which is a clear sin. 50
