O you who believe, do not perform your service of prayer when you are intoxicated until you are sure of what you are saying, nor when in a state of seminal pollution, until you have taken a bath, except when you are travelling. But in case you are ill or are travelling, or you have relieved yourself of nature's call, or cohabited with a woman, and cannot find water, then take wholesome dust and pass it over your face and hands: God is benign 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 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 Jews take certain words out of context and by twisting their tongues to make a jest out of the true religion, say, "We heard and (in our hearts) disobeyed. (Muhammad) ra`ina (be kind to us) but they intend thereby (the meaning in their own language): "Listen! May God turn you deaf." They should have said, "We heard and obeyed. (Muhammad) listen and consider our question." This would have been better for them and more righteous. God has condemned them for their disbelief, thus, no one, except a few among them, will have faith. 46 O you who have been granted revelation [aforetime]! Believe in what We have [now] bestowed from on high in confirmation of whatever [of the truth] you already possess, lest We efface your hopes and bring them to an end - just as We rejected those people who broke the Sabbath: for God's will is always done. 47 Verily, Allah forgives not that partners should be set up with him in worship, but He forgives except that (anything else) to whom He pleases, and whoever sets up partners with Allah in worship, he has indeed invented a tremendous 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 forge lies against Allah, and it is sufficient for a clear sin. 50
