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 Hast thou not turned Thy vision to those who were given a portion of the Book? they traffic in error, and wish that ye should lose the right path. 44 God knows who are your enemies. You need to have no guardian or helper other than God. 45 Among the Jews are those who distort words from their [proper] usages and say, "We hear and disobey" and "Hear but be not heard" and "Ra'ina," twisting their tongues and defaming the religion. And if they had said [instead], "We hear and obey" and "Wait for us [to understand]," it would have been better for them and more suitable. But Allah has cursed them for their disbelief, so they believe not, except for a few. 46 O People of the Book, believe in what We have sent down, fulfilling [the predictions] that is with you, before We destroy [your sense of] direction, so as to confound or reject you, as We rejected those who broke the Sabbath: God's command is always carried out. 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 Did you not see those who proclaim their piety (cleanliness of deeds)? In fact Allah purifies whomever He wills, and no injustice, even equal to the hair upon a date seed will be done to them. 49 See how they fabricate lies against Allah! And this is a sufficient manifest sin. 50
