Believers! Do not draw near to the Prayer while you are intoxicated until you know what you are saying nor while you are defiled - save when you are travelling - until you have washed yourselves. If you are either ill or travelling or have satisfied a want of nature or have had contact with women and can find no water, then betake yourselves to pure earth, passing with it lightly over your face and your hands. Surely Allah is All-Relenting, All-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 And Allah best knows your enemies; and Allah suffices as a Guardian, and Allah suffices 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 O you who have been granted the Book! Do believe in what We have (now) revealed, which confirms the revelation which you already possess. Do this before We alter countenances, turning them backwards, or lay a curse upon them as We cursed the Sabbath-men. Bear in mind that Allah's command is done. 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 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 Behold how they fabricate a lie against Allah! and sufficeth that as a manifest sin. 50
