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 knows best your enemies. It is sufficient that Allah is the Guardian, and it is sufficient that Allah is the 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 Verily, Allah forgives not that partners should be set up with him in worship, but He forgives except that (anything else) to whom He pleases, and whoever sets up partners with Allah in worship, he has indeed invented a tremendous sin. 48 Did you not see those who proclaim their piety (cleanliness of deeds)? In fact Allah purifies whomever He wills, and no injustice, even equal to the hair upon a date seed will be done to them. 49 Look, how they invent a lie against Allah, and enough is that as a manifest sin. 50
