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 Observest thou not those unto whom was vouchsafed a portion of the book purchasing error, and desiring that ye would err as regards the way! 44 But Allah knows best your enemies. It is sufficient that Allah is the Guardian, and it is sufficient that Allah is the Helper. 45 Some Jews take words out of their context and say, "We have heard, but we disobey," or "Hear without listening." And they say "Look at us," twisting the phrase with their tongues so as to disparage religion. But if they had said, "We hear and we obey," and "Listen to us and look at us with favour," that would have been better and more proper for them. God has rejected them for their defiance so that they shall not believe, except a few of them. 46 O you who have been given the Scripture (Jews and Christians)! Believe in what We have revealed (to Muhammad SAW) confirming what is (already) with you, before We efface faces (by making them like the back of necks; without nose, mouth, eyes, etc.) and turn them hindwards, or curse them as We cursed the Sabbath-breakers. And the Commandment of Allah is always executed. 47 Allah does not forgive (the sin of inventing an) association with Him, but He forgives other (sins) to whomsoever He will. He who associates with Allah has invented a great sin. 48 Have you not seen those who consider themselves pure? It is indeed God who purifies whoever He pleases and none shall be wronged by as much as a hair's breadth. 49 See how they fabricate lies against Allah! And this is a sufficient manifest sin. 50
