Believers, do not approach your prayers when you are drunk, until you understand what you say, nor when you are in a state of impurity, -- except when you are on a journey -- till you have bathed. And if you are ill, or on a journey or have relieved yourselves or when you have consorted with women and you cannot find any water, then find some clean sand and wipe your face and your hands with it. God is gracious and forgiving. 43 Have you not considered those to whom a portion of the Book has been given? They buy error and desire that you should go astray from the way. 44 God is quite aware as to who your enemies are; God suffices as a patron, and God suffices as a supporter. 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 people of the Book, believe in what We have revealed, which confirms what is already with you before We disfigure your visages and turn your faces about and curse you, as We did with those who had broken the Sabbath; and what God decrees comes to pass. 47 Allah does not forgive (the sin of inventing an) association with Him, but He forgives other (sins) to whomsoever He will. He who associates with Allah has invented a great sin. 48 Hast thou not regarded those who purify themselves? Nay; only God purifies whom He will; and they shall not be wronged a single date-thread. 49 Behold how they fabricate a lie against Allah! and sufficeth that as a manifest sin. 50
