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, [O Muhammad], "The Pure Spirit has brought it down from your Lord in truth to make firm those who believe and as guidance and good tidings to the Muslims." 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 Only they forge the lie who do not believe in Allah's communications, and these are the liars. 105 Whosoever denies having once believed -- unless he is forced to do so while his heart enjoys the peace of faith -- and opens his mind to disbelief will suffer the wrath of God. Their punishment will be great, 106 That is because they loved the life of the world above the Hereafter, and because Allah guideth not an infidel 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 So it occurred that they are the losers in the Hereafter. 109 ۞ Then, indeed your Lord, to those who emigrated after they had been compelled [to renounce their religion] and thereafter fought [for the cause of Allah] and were patient - indeed, your Lord, after that, is Forgiving and Merciful 110
