O you who have believed, do not approach prayer while you are intoxicated until you know what you are saying or in a state of janabah, except those passing through [a place of prayer], until you have washed [your whole body]. And if you are ill or on a journey or one of you comes from the place of relieving himself or you have contacted women and find no water, then seek clean earth and wipe over your faces and your hands [with it]. Indeed, Allah is ever Pardoning 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 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 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 Behold how they attribute their own lying inventions to God - than which there is no sin more obvious. 50
