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 to whom a portion of the Book was given purchasing error and wishing that you should err from the Path? 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 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 Ye who are vouchsafed the Book believe in that which We have sent down confirming that which is with you, ere We alter countenances and turn them into their hinder parts, or We might curse them even as We cursed the fellows of the Sabt; and Allah's command is ever fulfilled. 47 Surely Allah does not forgive that anything should be associated with Him, and forgives what is besides that to whomsoever He pleases; and whoever associates anything with Allah, he devises indeed a great sin. 48 Art thou not aware of those who consider themselves pure? Nay, but it is God who causes whomever He wills to grow in purity; and none shall be wronged by as much as a hair's breadth. 49 Behold how they fabricate a lie against Allah! and sufficeth that as a manifest sin. 50
