O you who believe, do not perform your service of prayer when you are intoxicated until you are sure of what you are saying, nor when in a state of seminal pollution, until you have taken a bath, except when you are travelling. But in case you are ill or are travelling, or you have relieved yourself of nature's call, or cohabited with a woman, and cannot find water, then take wholesome dust and pass it over your face and hands: God is benign and forgiving. 43 Have you not seen those to whom a portion of the Book was given? They purchased error for themselves, and wish that you too lose the right way? 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 Ye who are vouchsafed the Book believe in that which We have sent down confirming that which is with you, ere We alter countenances and turn them into their hinder parts, or We might curse them even as We cursed the fellows of the Sabt; and Allah's command is ever fulfilled. 47 VERILY, God does not forgive the ascribing of divinity to aught beside Him, although He forgives any lesser sin unto whomever He wills: for he who ascribes divinity to aught beside God has indeed contrived an awesome 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 Behold! how they invent a lie against Allah! but that by itself is a manifest sin! 50
