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 Tell them: "It is the spirit of holiness that has brought it down, by stages, from your Lord so that it might bring firmness to those who believe, and guidance to the Right Way, and give glad tidings of felicity and success to those who submit to Allah." 102 We know indeed that they say, "It is a man that teaches him." The tongue of him they wickedly point to is notably foreign, while this is Arabic, pure and clear. 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 It is those who believe not in the Signs of Allah, that forge falsehood: it is they who lie! 105 The one who disbelieves in Allah after accepting faith – except him who is forced to and whose heart is still firmly upon faith – but whoever is wholeheartedly a disbeliever, upon them is the wrath of Allah; and for them is a great punishment. 106 That is because they have chosen the life of the world rather than the Hereafter, and because Allah guideth not the disbelieving folk. 107 Those -- God has set a seal on their hearts, and their hearing, and their eyes, and those -- they are the heedless ones; 108 In the Everlasting Life, they shall assuredly be the losers. 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
