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 seen those who had received a portion of the Book trade misguidance and try to make you, too, go astray? 44 Allah knoweth best (who are) your enemies. Allah is sufficient as a Guardian, and Allah is sufficient as a Supporter. 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 you who have been given the Book! believe that which We have revealed, verifying what you have, before We alter faces then turn them on their backs, or curse them as We cursed the violaters of the Sabbath, and the command of Allah shall be executed. 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 Have you not seen those who consider themselves pure? It is indeed God who purifies whoever He pleases and none shall be wronged by as much as a hair's breadth. 49 Look how they forge lies against Allah, and it is sufficient for a clear sin. 50
