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 Did you not see those who received a portion of the Book, that they purchase error and wish that you too go astray from the right path? 44 God knows well your enemies; God suffices as a protector, God suffices as a helper. 45 Among those who have become Jews there are some who alter the words from their context, and make a malicious play with their tongues and seek to revile the true faith. They say: 'We have heard and we disobey' (sami'na wa 'asayna), 'Do hear us, may you turn dumb' (isma' ghayr musma') and 'Hearken to us' (ra'ina). It would indeed have been better for them and more upright if they had said: 'We have heard and we obey' (sami'na wa ata'na) and: 'Do listen to us, and look at us (with kindness)' (wa isma' wa unzurna). But Allah has cursed them because of their disbelief. Scarcely do they believe. 46 O you who were given the Scripture, believe in what We have sent down [to Muhammad], confirming that which is with you, before We obliterate faces and turn them toward their backs or curse them as We cursed the sabbath-breakers. And ever is the decree of Allah accomplished. 47 God does not forgive that compeers be ascribed to Him, though He may forgive aught else if He please. And he who ascribes compeers to God is guilty of the gravest 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 Look, how they invent a lie against Allah, and enough is that as a manifest sin. 50
