O you who believe! Approach not As-Salat (the prayer) when you are in a drunken state until you know (the meaning) of what you utter, nor when you are in a state of Janaba, (i.e. in a state of sexual impurity and have not yet taken a bath) except when travelling on the road (without enough water, or just passing through a mosque), till you wash your whole body. And if you are ill, or on a journey, or one of you comes after answering the call of nature, or you have been in contact with women (by sexual relations) and you find no water, perform Tayammum with clean earth and rub therewith your faces and hands (Tayammum). Truly, Allah is Ever Oft-Pardoning, Oft-Forgiving. 43 Have you not seen those who were given a portion of the Scripture, purchasing error [in exchange for it] and wishing you would lose the way? 44 Allah has full knowledge of your enemies, and Allah is Sufficient as a Wali (Protector), and Allah is Sufficient as a Helper. 45 Among those who have become Jews there are some who alter the words from their context, and make a malicious play with their tongues and seek to revile the true faith. They say: 'We have heard and we disobey' (sami'na wa 'asayna), 'Do hear us, may you turn dumb' (isma' ghayr musma') and 'Hearken to us' (ra'ina). It would indeed have been better for them and more upright if they had said: 'We have heard and we obey' (sami'na wa ata'na) and: 'Do listen to us, and look at us (with kindness)' (wa isma' wa unzurna). But Allah has cursed them because of their disbelief. Scarcely do they believe. 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 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 (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 Behold! how they invent a lie against Allah! but that by itself is a manifest sin! 50
