When We substitute one revelation for another,- and Allah knows best what He reveals (in stages),- they say, "Thou art but a forger": but most of them understand not. 101 Say: 'The Holy Spirit (Gabriel) brought it down from your Lord in truth to confirm those who believe, and to give guidance and glad tidings to those who surrender' 102 We know very well that they say: 'A mortal teaches him' The tongue of him at whom they hint is a nonArab; and this is a clear Arabic tongue. 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 As for anyone who denies God after having once attained to faith - and this, to be sure, does not apply to one who does it under duress, the while his heart remains true to his faith, but [only, to] him who willingly opens up his heart to a denial of the truth: upon all such [falls] God's condemnation, and tremendous suffering awaits them: 106 That is because they loved this present life above the Everlasting Life. Allah does not guide the unbelievers. 107 God has sealed their hearts, ears and eyes and they are not aware of it. 108 No doubt that in the hereafter 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
