Believers! Do not draw near to the Prayer while you are intoxicated until you know what you are saying nor while you are defiled - save when you are travelling - until you have washed yourselves. If you are either ill or travelling or have satisfied a want of nature or have had contact with women and can find no water, then betake yourselves to pure earth, passing with it lightly over your face and your hands. Surely Allah is All-Relenting, All-Forgiving. 43 Have you not seen those to whom a portion of the Book was given? They purchased error for themselves, and wish that you too lose the right 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 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, God does not forgive the ascribing of divinity to aught beside Him, although He forgives any lesser sin unto whomever He wills: for he who ascribes divinity to aught beside God has indeed contrived an awesome 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 invent a lie against Allah! but that by itself is a manifest sin! 50
