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 Allah has full knowledge of your enemies, and Allah is Sufficient as a Wali (Protector), and Allah is Sufficient 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 you who have been given the Book! believe that which We have revealed, verifying what you have, before We alter faces then turn them on their backs, or curse them as We cursed the violaters of the Sabbath, and the command of Allah shall be executed. 47 Surely Allah does not forgive that a partner be ascribed to Him, although He forgives any other sins for whomever He wills. He who associates anyone with Allah in His divinity has indeed forged a mighty lie and committed an awesome sin. 48 Have you not seen those who boast of their righteousness, even though it is Allah Who grants righteousness to whomsoever He wills? They are not wronged even as much as the husk of a date-stone (if they do not receive righteousness). 49 Look how they invent about Allah untruth, and sufficient is that as a manifest sin. 50
