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 Hast thou not regarded those who were given a share of the Book purchasing error, and desiring that you should also err from 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 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 People of the Book, have faith in the Quran that We have revealed to confirm your Book, before certain faces are changed and turned back. We shall condemn them as We did the people of the Sabbath about whom God's decree had decisively been ordained. 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 the people who call themselves pure? Yet God purifies whom He pleases, and none shall be wronged even the breadth of a thread. 49 Behold! how they invent a lie against Allah! but that by itself is a manifest sin! 50
