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 the people who were given a share of the Book, but who purchased only error, and wish that you also go astray? 44 Allah has full knowledge of your enemies, and Allah is Sufficient as a Wali (Protector), and Allah is Sufficient as a Helper. 45 Some Jews tampered with the words (altering) their places saying: 'We have heard and we disobey' and 'Hear, without hearing' and 'Observe us (Ra'ina, in Hebrew means evil)', twisting with their tongues traducing religion. But if they had said: 'We have heard and obey' and 'Hear' and 'Regard us' it would have been better for them, and more upright; but Allah has cursed them for their disbelief, so they do not believe, except a few. 46 O you who have been given the Scripture (Jews and Christians)! Believe in what We have revealed (to Muhammad SAW) confirming what is (already) with you, before We efface faces (by making them like the back of necks; without nose, mouth, eyes, etc.) and turn them hindwards, or curse them as We cursed the Sabbath-breakers. And the Commandment of Allah is always executed. 47 God does not forgive that compeers be ascribed to Him, though He may forgive aught else if He please. And he who ascribes compeers to God is guilty of the gravest sin. 48 Hast thou not seen those who praise themselves for purity? Nay, Allah purifieth whom He will, and they will not be wronged even the hair upon a date-stone. 49 See how they fabricate lies about God, which is a clear sin. 50
