O believers, draw not near to prayer when you are drunken until you know what you are saying, or defiled -- unless you are traversing a way -- until you have washed yourselves; but if you are sick, or on a journey, or if any of you comes from the privy, or you have touched women, and you can find no water, then have recourse to wholesome dust and wipe your faces and your hands; God is All-pardoning, 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 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 ye unto whom the Scripture hath been given! Believe in what We have revealed confirming that which ye possess, before We destroy countenances so as to confound them, or curse them as We cursed the Sabbath-breakers (of old time). The commandment of Allah is always executed. 47 God will not forgive anyone for associating something with Him, while He will forgive whoever He wishes for anything besides that. Whoever ascribes partners to God is guilty of a monstrous sin. 48 Have you not seen the people who call themselves pure? Yet God purifies whom He pleases, and none shall be wronged even the breadth of a thread. 49 See how they fabricate lies about God, which is a clear sin. 50
