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 seen the people who were given a share of the Book, but who purchased only error, and wish that you also go astray? 44 And Allah is most knowing of your enemies; and sufficient is Allah as an ally, and sufficient is Allah as a helper. 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 ye People of the Book! believe in what We have (now) revealed, confirming what was (already) with you, before We change the face and fame of some (of you) beyond all recognition, and turn them hindwards, or curse them as We cursed the Sabbath-breakers, for the decision of Allah Must be carried out. 47 God forgives not that aught should be with Him associated; less than that He forgives to whomsoever He will. Whoso associates with God anything, has indeed forged a mighty 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 See how they forge the lie against Allah, and this is sufficient as a manifest sin. 50
