Believers, do not pray when you are drunk, but, instead, wait until you can understand what you say. Also, do not pray when you have experienced a seminal discharge until after you have taken a bath, unless you are on a journey. If, while sick or on a journey, you can find no water after having defecated or after having had carnal relations, perform tayammum by touching your palms on the pure earth and wipe the (upper part of) your face and the backs of your hands. God is Gracious and All-forgiving. 43 Do you not know of those who were in possession of a portion of the Book? They buy up error and want you to lose your way. 44 And Allah is Knower of your enemies. Sufficieth Allah as a Friend and sufficieth Allah 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 you who were given the Scripture, believe in what We have sent down [to Muhammad], confirming that which is with you, before We obliterate faces and turn them toward their backs or curse them as We cursed the sabbath-breakers. And ever is the decree of Allah accomplished. 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 Have you not seen those who consider themselves pure? It is indeed God who purifies whoever He pleases and none shall be wronged by as much as a hair's breadth. 49 Behold! how they invent a lie against Allah! but that by itself is a manifest sin! 50
