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 But Allah hath full knowledge of your enemies: Allah is enough for a protector, and Allah is enough for a Helper. 45 Some among the Jews distort the words out of context and say (in place of the right words): "We have heard and do not obey;" and, "hear without hearing," and "listen to us," twisting their tongues and reviling the faith. But if they had said: "We have heard and obey," and, "hear and regard us," it would have been better for them and more appropriate. But God has disgraced them for their lack of belief; and so only a few of them believe. 46 O you who were given the Scripture, believe in what We have sent down [to Muhammad], confirming that which is with you, before We obliterate faces and turn them toward their backs or curse them as We cursed the sabbath-breakers. And ever is the decree of Allah accomplished. 47 Verily Allah shall not Forgive that aught be associated with Him, and He will forgive all else unto whomsoever He listeth. And whosoever associateth aught with Allah, he hath of a surety fabricated a mighty sin. 48 Have you not seen the people who call themselves pure? Yet God purifies whom He pleases, and none shall be wronged even the breadth of a thread. 49 See how they attribute their own lying inventions to God. This is in itself a flagrant sin! 50
