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 Have you not considered those to whom a portion of the Book has been given? They buy error and desire that you should go astray from the way. 44 God is quite aware as to who your enemies are; God suffices as a patron, and God suffices as a supporter. 45 Among those who are Jews, there are some who displace words from (their) right places and say: "We hear your word (O Muhammad SAW) and disobey," and "Hear and let you (O Muhammad SAW) hear nothing." And Ra'ina with a twist of their tongues and as a mockery of the religion (Islam). And if only they had said: "We hear and obey", and "Do make us understand," it would have been better for them, and more proper, but Allah has cursed them for their disbelief, so they believe not except a few. 46 You, to whom the Book was given, believe in that which We have sent down confirming that which you have, before We obliterate faces and turn them on their backs, or curse them as We cursed the people of the Sabbath. And the command of Allah is done. 47 God does not forgive that compeers be ascribed to Him, though He may forgive aught else if He please. And he who ascribes compeers to God is guilty of the gravest 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 attribute their own lying inventions to God - than which there is no sin more obvious. 50
