O Messenger! Do not be grieved on account of those who vie with one another in disbelieving: even though they be those who say with their mouths: 'We believe' even though their hearts have no faith; or they be Jews who have their ears eagerly turned to falsehood and spy for other people who did not chance to come to you, who pervert the words of Allah, taking them out of their proper context in order to distort their meaning. They say to people: 'If such and such teaching is given to you, accept it; if you are not given that, then beware! You can be of no avail to him whom Allah wills to fall into error. Those are the ones whose hearts Allah does not want to purify. For them there is degradation in this world and a mighty chastisement in the Next.
