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 Surely We know well that they say about you: "It is only a human being who teaches him," (notwithstanding) that he whom they maliciously hint at is of foreign tongue, while this (Qur'an) is plain Arabic speech. 103 (As for) those who do not believe in Allah's communications, surely Allah will not guide them, and they shall have a painful punishment. 104 Only they invent falsehood who believe not Allah's revelations, and (only) they are the 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 all this, because they hold this world's life in greater esteem than the life to come, and because God does not bestow His guidance upon people who deny the truth. 107 These are they upon whose hearts and hearing and sight Allah hath set a seal; and these! they are the negligent. 108 Without doubt, in the Hereafter they will perish. 109 ۞ Then lo! thy Lord - for those who became fugitives after they had been persecuted, and then fought and were steadfast - lo! thy Lord afterward is (for them) indeed Forgiving, Merciful. 110
