O Believers, do not offer the Prayer while you are intoxicated,66 for Prayer should be offered only when you know what you are saying.67 Likewise, do not offer the Prayer if you are "unclean"68 until you take your bath, except when passing on the way:69 and if you are sick or on a journey .or if any one of you has relieved himself or you have touched70 women and can find no water, then cleanse yourselves with pure dust by rubbing it on your face and hands;71 no doubt Allah is Lenient and Forgiving. Have you ever considered the case of those who have been given a portion of the scriptures?72 They themselves purchase deviation and wish you, too, to go astray from the Right Way: Allah knows your enemies well and Allah suffices you for protection and for help. Some of those, who have become Jews,73 pervert74 words out of their context and twist their tongues in order to malign the true Faith and say "sami 'ina75 wa 'asaina " and "Isma' ghaira musma `in76 and ''Ra 'ina77 . But, if they had said instead, "sami `ina wa ata "ana, " "Isma "' and " Unzurna," it would have been better for themselves and a more upright way. As Allah has cursed them for their disbelief, they are little disposed to believe. O you to whom the Book had been given! Believe in the Book We have sent down now, confirming the Book you already have with you,78 believe in it before We distort faces and set them backwards, or lay Our curse on them as We laid Our curse on the Sabbath breakers:79 and remember that Allah's Command is surely carried into effect. Shirk is the only sin that Allah does not forgive,80 and He forgives whomsoever He pleases, other sins than this,81 for whosoever associates any other partner with Allah, does indeed forge a big lie and commit the most heinous sin. Have you also marked those, who speak very highly of their own purity? However, Allah alone purifies whomever He pleases (and if they are not being purified), no injustice is being done to them in the least. Just behold! they do not hesitate to invent lies about Allah, and this sin alone suffices to show that they are manifest sinners.
