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 hath delivered it from thy Lord with truth, that it may confirm (the faith of) those who believe, and as guidance and good tidings for those who have surrendered (to Allah). 102 And assuredly We know that they say: it is only a human being who teacheth him. The speech of him unto whom they incline is foreign while this is Arabic speech plain. 103 Verily! Those who believe not in the Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) of Allah, Allah will not guide them and theirs will be a painful torment. 104 Only those who do not believe in Allah’s signs attribute lies and fabrications; and they themselves are liars. 105 Whosoever disbelieves in Allah after believing except he who is forced while his heart remains in his belief but he who opens his chest for disbelief, shall receive the Anger of Allah and for such awaits a mighty punishment. 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 They whose hearts and whose hearing and whose sight God has sealed - it is they, they who are heedless! 108 Without doubt, in the Hereafter they will perish. 109 ۞ But verily thy Lord,- to those who leave their homes after trials and persecutions,- and who thereafter strive and fight for the faith and patiently persevere,- Thy Lord, after all this is oft-forgiving, Most Merciful. 110
