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 And Allah is most knowing of your enemies; and sufficient is Allah as an ally, and sufficient is Allah as a helper. 45 Some of those who are Jews change words from their context and say: "We hear and disobey; hear thou as one who heareth not" and "Listen to us!" distorting with their tongues and slandering religion. If they had said: "We hear and we obey: hear thou, and look at us" it had been better for them, and more upright. But Allah hath cursed them for their disbelief, so they believe not, save a few. 46 You, to whom the Book was given, believe in that which We have sent down confirming that which you have, before We obliterate faces and turn them on their backs, or curse them as We cursed the people of the Sabbath. And the command of Allah is done. 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 Art thou not aware of those who consider themselves pure? Nay, but it is God who causes whomever He wills to grow in purity; and none shall be wronged by as much as a hair's breadth. 49 See how they forge the lie against Allah, and this is sufficient as a manifest sin. 50
