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 Allah knows your enemies better and Allah suffices as a protector and Allah suffices as a helper. 45 Some Jews tampered with the words (altering) their places saying: 'We have heard and we disobey' and 'Hear, without hearing' and 'Observe us (Ra'ina, in Hebrew means evil)', twisting with their tongues traducing religion. But if they had said: 'We have heard and obey' and 'Hear' and 'Regard us' it would have been better for them, and more upright; but Allah has cursed them for their disbelief, so they do not believe, except a few. 46 O you who have been granted revelation [aforetime]! Believe in what We have [now] bestowed from on high in confirmation of whatever [of the truth] you already possess, lest We efface your hopes and bring them to an end - just as We rejected those people who broke the Sabbath: for God's will is always done. 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 Have you not seen those who exalt themselves? Rather, Allah purifies whom He will and they shall not be wronged a single tissue that covers a date stone. 49 Behold how they fabricate a lie against Allah! and sufficeth that as a manifest sin. 50
