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 Did you not see those who received a portion of the Book, that they purchase error and wish that you too go astray from the right path? 44 God knows well your enemies; God suffices as a protector, God suffices as a helper. 45 Some of those who are Jews change words from their context and say: "We hear and disobey; hear thou as one who heareth not" and "Listen to us!" distorting with their tongues and slandering religion. If they had said: "We hear and we obey: hear thou, and look at us" it had been better for them, and more upright. But Allah hath cursed them for their disbelief, so they believe not, save a few. 46 O you who have been granted the Book! Do believe in what We have (now) revealed, which confirms the revelation which you already possess. Do this before We alter countenances, turning them backwards, or lay a curse upon them as We cursed the Sabbath-men. Bear in mind that Allah's command is done. 47 God does not forgive the sin of considering others equal to Him, but He may choose to forgive other sins. Whoever believes in other gods besides Him has indulged in a great 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 fabricate a lie against Allah! and sufficeth that as a manifest sin. 50
