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 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 Allah has full knowledge of your enemies, and Allah is Sufficient as a Wali (Protector), and Allah is Sufficient as a Helper. 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 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 Allah forgiveth not that partners should be set up with Him; but He forgiveth anything else, to whom He pleaseth; to set up partners with Allah is to devise a sin Most heinous indeed. 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 Consider how they create lies about God? This alone is a grave sin. 50
