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 Observest thou not those unto whom was vouchsafed a portion of the book purchasing error, and desiring that ye would err as regards the way! 44 Allah has full knowledge of your enemies, and Allah is Sufficient as a Wali (Protector), and Allah is Sufficient as a Helper. 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 were given the Scripture, believe in what We have sent down [to Muhammad], confirming that which is with you, before We obliterate faces and turn them toward their backs or curse them as We cursed the sabbath-breakers. And ever is the decree of Allah accomplished. 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 (Muhammad), have you seen those who try to purify themselves? They should know that God only purifies whomever He wants and that the slightest wrong will not be done to such people. 49 Look, how they invent a lie against Allah, and enough is that as a manifest sin. 50
