O Ye who believe! approach not prayer while ye are intoxicated until ye know that which ye say, nor yet while ye are polluted, save when ye be way faring, until ye have washed yourselves. And if ye be ailing or on a journey, or one of you cometh from the privy or ye have touched women, and ye find not water, then betake your selves to clean earth and wipe your faces and your hands therewith; verily Allah is ever Pardoning, 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 knows best your enemies. It is sufficient that Allah is the Guardian, and it is sufficient that Allah is the 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 People of the Book, believe in what We have sent down, fulfilling [the predictions] that is with you, before We destroy [your sense of] direction, so as to confound or reject you, as We rejected those who broke the Sabbath: God's command is always carried out. 47 Verily Allah shall not Forgive that aught be associated with Him, and He will forgive all else unto whomsoever He listeth. And whosoever associateth aught with Allah, he hath of a surety fabricated a mighty sin. 48 Did you not see those who proclaim their piety (cleanliness of deeds)? In fact Allah purifies whomever He wills, and no injustice, even equal to the hair upon a date seed will be done to them. 49 See how they forge the lie against Allah, and this is sufficient as a manifest sin. 50
