Believers, do not approach your prayers when you are drunk, until you understand what you say, nor when you are in a state of impurity, -- except when you are on a journey -- till you have bathed. And if you are ill, or on a journey or have relieved yourselves or when you have consorted with women and you cannot find any water, then find some clean sand and wipe your face and your hands with it. God is gracious and 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 God knows well your enemies; God suffices as a protector, God suffices as a 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 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 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 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
