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 Observest thou not those unto whom was vouchsafed a portion of the book purchasing error, and desiring that ye would err as regards the way! 44 Allah well knows your enemies; Allah is Sufficient as a Guardian, and Allah is Sufficient as a Supporter. 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 People of the Book! believe in what We have (now) revealed, confirming what was (already) with you, before We change the face and fame of some (of you) beyond all recognition, and turn them hindwards, or curse them as We cursed the Sabbath-breakers, for the decision of Allah Must be carried out. 47 Indeed, Allah does not forgive association with Him, but He forgives what is less than that for whom He wills. And he who associates others with Allah has certainly fabricated 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 Consider how they create lies about God? This alone is a grave sin. 50
