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 But Allah knows best your enemies. It is sufficient that Allah is the Guardian, and it is sufficient that Allah is the Helper. 45 Of the Jews there are those who displace words from their (right) places, and say: "We hear and we disobey"; and "Hear what is not Heard"; and "Ra'ina"; with a twist of their tongues and a slander to Faith. If only they had said: "What hear and we obey"; and "Do hear"; and "Do look at us"; it would have been better for them, and more proper; but Allah hath cursed them for their Unbelief; and but few of them will believe. 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 Surely Allah does not forgive that anything should be associated with Him, and forgives what is besides that to whomsoever He pleases; and whoever associates anything with Allah, he devises indeed a great sin. 48 Did you not see those who proclaim their piety (cleanliness of deeds)? In fact Allah purifies whomever He wills, and no injustice, even equal to the hair upon a date seed will be done to them. 49 Look, how they invent a lie against Allah, and enough is that as a manifest sin. 50
