When We exchange a verse for another and Allah knows best what He is sending down they say: 'You are but a forger' No, most of them do not know. 101 Say: The holy Spirit hath delivered it from thy Lord with truth, that it may confirm (the faith of) those who believe, and as guidance and good tidings for those who have surrendered (to Allah). 102 We know that they say a mere mortal has taught it (the Quran) to him (Muhammad). The language of the person whom they think has taught it to him is not Arabic. This (the Quran) is in illustrious Arabic. 103 God will not guide those who will not believe in the signs of God; and theirs will be a painful punishment. 104 They only forge falsehood, who believe not in the signs of God, and those -- they are the liars. 105 Whosoever disbelieves in Allah after believing except he who is forced while his heart remains in his belief but he who opens his chest for disbelief, shall receive the Anger of Allah and for such awaits a mighty punishment. 106 That is because they love the life of this world more than the Hereafter; and Allah does not guide those who are ungrateful to Allah for His favours. 107 They whose hearts and whose hearing and whose sight God has sealed - it is they, they who are heedless! 108 and in the life to come, they will surely be the losers. 109 ۞ Then, verily, thy Lord unto those who have emigrated after they had been tempted and have thereafter striven hard and endured, verily thy Lord thereafter is Forgiving, Merciful. 110
