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 Have you not seen those who were given a portion of the book (the Jews), purchasing the wrong path, and wish that you should go astray from the Right Path? 44 But God knows your enemies well: and sufficient is God to protect you, and sufficient is God for all help. 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 you who were given the Scripture, believe in what We have sent down [to Muhammad], confirming that which is with you, before We obliterate faces and turn them toward their backs or curse them as We cursed the sabbath-breakers. And ever is the decree of Allah accomplished. 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 Hast thou not observed those who hold themselves purified? Nay! Allah purifieth whomsoever He will, and they shall not be wronged a whit. 49 See how they forge lies about Allah! This in itself is a manifest sin. 50
