Believers, do not come close to prayer when you are drunk, until you know what you are saying, nor when you are in a state of impurity, unless you are crossing through the way (prayer area) until you have bathed yourselves. If you are ill or on a journey, or if any of you comes from the toilet or you have touched women, and you cannot find water, so touch pure dust and wipe your faces and your hands. Allah is the Pardoner, the Forgiver. 43 Do you not know of those who were in possession of a portion of the Book? They buy up error and want you 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 Allah does not forgive (the sin of inventing an) association with Him, but He forgives other (sins) to whomsoever He will. He who associates with Allah has invented a great sin. 48 (Muhammad), have you seen those who try to purify themselves? They should know that God only purifies whomever He wants and that the slightest wrong will not be done to such people. 49 Behold how they attribute their own lying inventions to God - than which there is no sin more obvious. 50
