O believers, draw not near to prayer when you are drunken until you know what you are saying, or defiled -- unless you are traversing a way -- until you have washed yourselves; but if you are sick, or on a journey, or if any of you comes from the privy, or you have touched women, and you can find no water, then have recourse to wholesome dust and wipe your faces and your hands; God is All-pardoning, All-forgiving. 43 Have you not seen those who were given a portion of the Scripture, purchasing error [in exchange for it] and wishing you would lose the way? 44 And Allah is most knowing of your enemies; and sufficient is Allah as an ally, and sufficient is Allah as 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 O people of the Book, believe in what We have revealed, which confirms what is already with you before We disfigure your visages and turn your faces about and curse you, as We did with those who had broken the Sabbath; and what God decrees comes to pass. 47 Verily Allah shall not Forgive that aught be associated with Him, and He will forgive all else unto whomsoever He listeth. And whosoever associateth aught with Allah, he hath of a surety fabricated a mighty 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 See how they forge the lie against Allah, and this is sufficient as a manifest sin. 50
