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 the people who were given a share of the Book, but who purchased only error, and wish that you also go astray? 44 And Allah is most knowing of your enemies; and sufficient is Allah as an ally, and sufficient is Allah as a helper. 45 Some Jews take certain words out of context and by twisting their tongues to make a jest out of the true religion, say, "We heard and (in our hearts) disobeyed. (Muhammad) ra`ina (be kind to us) but they intend thereby (the meaning in their own language): "Listen! May God turn you deaf." They should have said, "We heard and obeyed. (Muhammad) listen and consider our question." This would have been better for them and more righteous. God has condemned them for their disbelief, thus, no one, except a few among them, will have faith. 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 Verily Allah shall not Forgive that aught be associated with Him, and He will forgive all else unto whomsoever He listeth. And whosoever associateth aught with Allah, he hath of a surety fabricated a mighty 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 Behold! how they invent a lie against Allah! but that by itself is a manifest sin! 50
