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 seen those to whom a portion of the Book was given? They purchased error for themselves, and wish that you too lose the right way? 44 Allah knows your enemies better and Allah suffices as a protector and Allah suffices as a 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 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
