O People who Believe! Do not approach the prayer when you are intoxicated until you have the sense to understand what you say, nor in the state of impurity until you have bathed except while travelling; and if you are ill or on a journey or one of you returns from answering the call of nature or you have cohabited with women, and you do not find water, then cleanse (yourself) with clean soil – therefore stroke your faces and your hands with it; indeed Allah is Most Pardoning, Oft Forgiving. 43 Did you not see those who received a portion of the Book, that they purchase error and wish that you too go astray from the right path? 44 But Allah hath full knowledge of your enemies: Allah is enough for a protector, and Allah is enough for 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 the Book! Do believe in what We have (now) revealed, which confirms the revelation which you already possess. Do this before We alter countenances, turning them backwards, or lay a curse upon them as We cursed the Sabbath-men. Bear in mind that Allah's command is 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 (Muhammad), have you seen those who try to purify themselves? They should know that God only purifies whomever He wants and that the slightest wrong will not be done to such people. 49 See how they forge the lie against Allah, and this is sufficient as a manifest sin. 50
