O you who believe, do not perform your service of prayer when you are intoxicated until you are sure of what you are saying, nor when in a state of seminal pollution, until you have taken a bath, except when you are travelling. But in case you are ill or are travelling, or you have relieved yourself of nature's call, or cohabited with a woman, and cannot find water, then take wholesome dust and pass it over your face and hands: God is benign and 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 Allah knows your enemies better and Allah suffices as a protector and Allah suffices as a helper. 45 Of those who are Judaised, are they who pervert words from their meanings and say: We hear and we disobey, and: hear thou without being made to hear, and RA'INA, twisting their tongues and scoffing at the faith! And had they said: we hear and obey, and: hear thou, and: UNZURNA, it had surely been better for them and more upright. But Allah hath cursed them for their infidelity, wherefore they shall not believe, save 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 God does not forgive the sin of considering others equal to Him, but He may choose to forgive other sins. Whoever believes in other gods besides Him has indulged in a great 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 attribute their own lying inventions to God. This is in itself a flagrant sin! 50
