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 to whom a portion of the Book was given? They purchased error for themselves, and wish that you too lose the right way? 44 Allah well knows your enemies; Allah is Sufficient as a Guardian, and Allah is Sufficient as a Supporter. 45 Of those who are Judaised, are they who pervert words from their meanings and say: We hear and we disobey, and: hear thou without being made to hear, and RA'INA, twisting their tongues and scoffing at the faith! And had they said: we hear and obey, and: hear thou, and: UNZURNA, it had surely been better for them and more upright. But Allah hath cursed them for their infidelity, wherefore they shall not believe, save a few. 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 Lo! Allah forgiveth not that a partner should be ascribed unto Him. He forgiveth (all) save that to whom He will. Whoso ascribeth partners to Allah, he hath indeed invented a tremendous 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 See how they fabricate lies against Allah! And this is a sufficient manifest sin. 50
