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 Hast thou not turned Thy vision to those who were given a portion of the Book? they traffic in error, and wish that ye should lose the right path. 44 But God knows your enemies well: and sufficient is God to protect you, and sufficient is God for all help. 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 People of the Book! believe in what We have (now) revealed, confirming what was (already) with you, before We change the face and fame of some (of you) beyond all recognition, and turn them hindwards, or curse them as We cursed the Sabbath-breakers, for the decision of Allah Must be carried out. 47 God will not forgive anyone for associating something with Him, while He will forgive whoever He wishes for anything besides that. Whoever ascribes partners to God is guilty of a monstrous 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 See how they forge the lie against Allah, and this is sufficient as a manifest sin. 50
