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 Proclaim, “The Holy Spirit* has rightly brought it down from your Lord, to make the believers steadfast, and a guidance and glad tidings for the Muslims.” (* Angel Jibreel – peace and blessings be upon him.) 102 And We know well that they say: Only a man teacheth him. The speech of him at whom they falsely hint is outlandish, and this is clear 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 Those who do not believe in the miracles of God invent lies and they are 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 This is because the worldly life was dearer to them than the Hereafter; and because Allah does not guide such 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 They will surely be losers in the life to come, 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
