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 Observest thou not those unto whom was vouchsafed a portion of the book purchasing error, and desiring that ye would err as regards the way! 44 Allah knoweth best (who are) your enemies. Allah is sufficient as a Guardian, and Allah is sufficient as a Supporter. 45 Some Jews take certain words out of context and by twisting their tongues to make a jest out of the true religion, say, "We heard and (in our hearts) disobeyed. (Muhammad) ra`ina (be kind to us) but they intend thereby (the meaning in their own language): "Listen! May God turn you deaf." They should have said, "We heard and obeyed. (Muhammad) listen and consider our question." This would have been better for them and more righteous. God has condemned them for their disbelief, thus, no one, except a few among them, will have faith. 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 God will not forgive anyone for associating something with Him, while He will forgive whoever He wishes for anything besides that. Whoever ascribes partners to God is guilty of a monstrous sin. 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 Look, how they invent a lie against Allah, and enough is that as a manifest sin. 50
