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 ART THOU NOT aware of those who, having been granted their share of the divine writ, now barter it away for error, and want you [too] to lose your way? 44 But God knows best who are your enemies: and none can befriend as God does, and none can give succour as God does. 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 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 Undoubtedly Allah does not forgive (the sin of) disbelieving in Him and forgives anything lower than it to whomever He wills; and whoever ascribes partners to Allah has invented a tremendous sin. 48 Have you not seen those who consider themselves pure? It is indeed God who purifies whoever He pleases and none shall be wronged by as much as a hair's breadth. 49 Look how they invent about Allah untruth, and sufficient is that as a manifest sin. 50
