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 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 It is only those who believe not in the Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) of Allah, who fabricate falsehood, and it is they who are liars. 105 No one verbally denounces his faith in God - unless he is forced - but his heart is confident about his faith. But those whose breasts have become open to disbelief will be subject to the wrath of God and will suffer 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 These are they on whose hearts and their hearing and their eyes Allah has set a seal, and these are the heedless ones. 108 They will surely be losers in the life to come, 109 ۞ Yet surely your Lord, with respect to those who fly after they are persecuted, then they struggle hard and are patient, most surely your Lord after that is Forgiving, Merciful. 110
