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 thou: the Holy Spirit hath brought it down from thy Lord with truth, that it may establish those who believe, and as a guidance and glad tidings unto the Muslims. 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 Those that believe not in the signs of God, God will not guide; there awaits them a painful chastisement. 104 They only forge falsehood, who believe not in the signs of God, and those -- they are the liars. 105 Whoever disbelieved in Allah after his belief, except him who is forced thereto and whose heart is at rest with Faith but such as open their breasts to disbelief, on them is wrath from Allah, and theirs will be a great torment. 106 This is because they prefer the life of this world to the Hereafter and because God does not guide those who deny the truth. 107 Those are the ones over whose hearts and hearing and vision Allah has sealed, and it is those who are the heedless. 108 No doubt that in the hereafter they will be the losers. 109 ۞ And surely your Lord will be Most Forgiving and Most Merciful towards those who left their homes after they were persecuted, and who thereafter struggled hard and remained constant. 110
