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 Allah hath full knowledge of your enemies: Allah is enough for a protector, and Allah is enough for 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 You who have been given the Book, believe in what We have sent down, confirming what is with you, before We obliterate faces, and turn them upon their backs, or curse them as We cursed the Sabbath-men, and God's command is done. 47 God does not forgive the sin of considering others equal to Him, but He may choose to forgive other sins. Whoever believes in other gods besides Him has indulged in a great 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 See how they forge lies about Allah! This in itself is a manifest sin. 50
