Believers, do not come close to prayer when you are drunk, until you know what you are saying, nor when you are in a state of impurity, unless you are crossing through the way (prayer area) until you have bathed yourselves. If you are ill or on a journey, or if any of you comes from the toilet or you have touched women, and you cannot find water, so touch pure dust and wipe your faces and your hands. Allah is the Pardoner, the Forgiver. 43 Do you not know of those who were in possession of a portion of the Book? They buy up error and want you to lose your way. 44 God knows who are your enemies. You need to have no guardian or helper other than God. 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 Undoubtedly Allah does not forgive (the sin of) disbelieving in Him and forgives anything lower than it to whomever He wills; and whoever ascribes partners to Allah has invented a tremendous sin. 48 Have you not seen those who claim themselves to be pure? Rather, Allah purifies whom He wills, and injustice is not done to them, [even] as much as a thread [inside a date seed]. 49 See, how they invent lies about Allah! That of itself is flagrant sin. 50
