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 Tell them: "It is the spirit of holiness that has brought it down, by stages, from your Lord so that it might bring firmness to those who believe, and guidance to the Right Way, and give glad tidings of felicity and success to those who submit to Allah." 102 And certainly We know that they say: Only a mortal teaches him. The tongue of him whom they reproach is barbarous, and this is clear Arabic tongue. 103 Lo! those who disbelieve the revelations of Allah, Allah guideth them not and theirs will be a painful doom. 104 Only those who do not believe in Allah’s signs attribute lies and fabrications; and they themselves are liars. 105 Whoso disbelieves in God, after he has believed -- excepting him who has been compelled, and his heart is still at rest in his belief -- but whosoever's breast is expanded in unbelief, upon them shall rest anger from God, and there awaits them a mighty chastisement; 106 This is because they love this world's life more than the hereafter, and because Allah does not guide the unbelieving people. 107 These are the ones whose hearts, ears, and eyes Allah has sealed; and they are the neglectful. 108 without a doubt, in the world to come they will 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
