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 Hast thou not regarded those who were given a share of the Book purchasing error, and desiring that you should also err from the way? 44 But God knows best who are your enemies: and none can befriend as God does, and none can give succour as God does. 45 Among the Jews are those who distort words from their [proper] usages and say, "We hear and disobey" and "Hear but be not heard" and "Ra'ina," twisting their tongues and defaming the religion. And if they had said [instead], "We hear and obey" and "Wait for us [to understand]," it would have been better for them and more suitable. But Allah has cursed them for their disbelief, so they believe not, except for a few. 46 O you who have been given the Book! believe that which We have revealed, verifying what you have, before We alter faces then turn them on their backs, or curse them as We cursed the violaters of the Sabbath, and the command of Allah shall be 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 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 forge the lie against Allah, and this is sufficient as a manifest sin. 50
