And when We exchange a verse in the place of another verse and God knows very well what He is sending down -- they say, 'Thou art a mere forger!' Nay, but the most of them have no knowledge. 101 Say, "The Holy Spirit has brought it down as truth from your Lord, so that He may strengthen those who believe, and also as guidance and as good tidings for those who submit." 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 do not believe in His miracles. They will suffer a painful punishment. 104 Only they forge the lie who do not believe in Allah's communications, and these are the liars. 105 The one who disbelieves in Allah after accepting faith – except him who is forced to and whose heart is still firmly upon faith – but whoever is wholeheartedly a disbeliever, upon them is the wrath of Allah; and for them is a great punishment. 106 This is because they have given preference to this life over the life to come and God does not guide disbelieving people. 107 Those -- God has set a seal on their hearts, and their hearing, and their eyes, and those -- they are the heedless ones; 108 Assuredly, it is they, in the Hereafter, who will be the losers. 109 ۞ Then indeed your Lord – for those who migrated after they had been oppressed, and then fought and remained patient – indeed your Lord is then, surely, Oft Forgiving, Most Merciful. 110
