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 Have you not seen those who were given a portion of the Scripture, purchasing error [in exchange for it] and wishing you would lose the 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 of the Jews pervert words from their meanings saying, 'We have heard and we disobey' and 'Hear, and be thou not given to hear' and 'Observe us,' twisting with their tongues and traducing religion. 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 God has cursed them for their unbelief so they believe not except a few. 46 O you who have been granted revelation [aforetime]! Believe in what We have [now] bestowed from on high in confirmation of whatever [of the truth] you already possess, lest We efface your hopes and bring them to an end - just as We rejected those people who broke the Sabbath: for God's will is always 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 Hast thou not regarded those who purify themselves? Nay; only God purifies whom He will; and they shall not be wronged a single date-thread. 49 See how they forge lies about Allah! This in itself is a manifest sin. 50
