O YOU who have attained to faith! Do not attempt to pray while you are in a state of drunkenness, [but wait] until you know what you are saying; nor yet [while you are] in a state requiring total ablution, until you have bathed - except if you are travelling [and are unable to do so]. But if you are ill, or are travelling, or have just satisfied a want of nature, or have cohabited with a woman, and can find no water - then take resort to pure dust, passing [therewith] lightly over your face and your hands. Behold, God is indeed an absolver of sins, much-forgiving. 43 ART THOU NOT aware of those who, having been granted their share of the divine writ, now barter it away for error, and want you [too] 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 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 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 forgives not that aught should be with Him associated; less than that He forgives to whomsoever He will. Whoso associates with God anything, has indeed forged a mighty sin. 48 Hast thou not observed those who hold themselves purified? Nay! Allah purifieth whomsoever He will, and they shall not be wronged a whit. 49 See how they fabricate lies about God, which is a clear sin. 50
