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 ART THOU NOT aware of those who, having been granted their share of the divine writ, now barter it away for error, and want you [too] to lose your way? 44 And Allah best knows your enemies; and Allah suffices as a Guardian, and Allah suffices as a Helper. 45 Some of the Jews pervert words from their meanings saying, 'We have heard and we disobey' and 'Hear, and be thou not given to hear' and 'Observe us,' twisting with their tongues and traducing religion. 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 God has cursed them for their unbelief so they believe not except a few. 46 People of the Book, have faith in the Quran that We have revealed to confirm your Book, before certain faces are changed and turned back. We shall condemn them as We did the people of the Sabbath about whom God's decree had decisively been ordained. 47 Surely Allah does not forgive that a partner be ascribed to Him, although He forgives any other sins for whomever He wills. He who associates anyone with Allah in His divinity has indeed forged a mighty lie and committed an awesome sin. 48 Have you not seen those who boast of their righteousness, even though it is Allah Who grants righteousness to whomsoever He wills? They are not wronged even as much as the husk of a date-stone (if they do not receive righteousness). 49 Behold how they attribute their own lying inventions to God - than which there is no sin more obvious. 50
