Believers, do not pray when you are drunk, but, instead, wait until you can understand what you say. Also, do not pray when you have experienced a seminal discharge until after you have taken a bath, unless you are on a journey. If, while sick or on a journey, you can find no water after having defecated or after having had carnal relations, perform tayammum by touching your palms on the pure earth and wipe the (upper part of) your face and the backs of your hands. God is Gracious and All-forgiving. 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 And Allah best knows your enemies; and Allah suffices as a Guardian, 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 ye People of the Book! believe in what We have (now) revealed, confirming what was (already) with you, before We change the face and fame of some (of you) beyond all recognition, and turn them hindwards, or curse them as We cursed the Sabbath-breakers, for the decision of Allah Must be carried out. 47 Indeed, Allah does not forgive association with Him, but He forgives what is less than that for whom He wills. And he who associates others with Allah has certainly fabricated 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 Behold how they attribute their own lying inventions to God - than which there is no sin more obvious. 50
