Believers, do not approach your prayers when you are drunk, until you understand what you say, nor when you are in a state of impurity, -- except when you are on a journey -- till you have bathed. And if you are ill, or on a journey or have relieved yourselves or when you have consorted with women and you cannot find any water, then find some clean sand and wipe your face and your hands with it. God is gracious and forgiving. 43 Seest thou not those unto whom a portion of the Scripture hath been given, how they purchase error, and seek to make you (Muslims) err from the right way? 44 But God knows best who are your enemies: and none can befriend as God does, and none can give succour as God does. 45 Among those of the Jewish faith there are some who distort the meaning of the [revealed] words, taking them out of their context and saying, [as it were,] "We have heard, but we disobey," and "Hear without hearkening," and "Hearken thou unto us, (O Muhammad)" - thus making a play with their tongues, and implying that the [true] Faith is false. And had they but said, "We have heard, and we pay heed," and "Hear [us,] and have patience with us," it would indeed have been for their own good, and more upright: but God has rejected them because of their refusal to acknowledge the truth - for it is in but few things that they believe. 46 O people of the Book, believe in what We have revealed, which confirms what is already with you before We disfigure your visages and turn your faces about and curse you, as We did with those who had broken the Sabbath; and what God decrees comes to pass. 47 God will not forgive anyone for associating something with Him, while He will forgive whoever He wishes for anything besides that. Whoever ascribes partners to God is guilty of a monstrous 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 Behold how they fabricate a lie against Allah! and sufficeth that as a manifest sin. 50
