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 has brought it down as truth from your Lord, so that He may strengthen those who believe, and also as guidance and as good tidings for those who submit." 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 Lo! those who disbelieve the revelations of Allah, Allah guideth them not and theirs will be a painful doom. 104 Only they forge the lie who do not believe in Allah's communications, and these are the liars. 105 Whoso disbelieveth in Allah after his belief - save him who is forced thereto and whose heart is still content with the Faith - but whoso findeth ease in disbelief: On them is wrath from Allah. Theirs will be an awful doom. 106 That is because they loved the life of the world above the Hereafter, and because Allah guideth not an infidel people. 107 God has sealed their hearts, ears and eyes and they are not aware of it. 108 So it occurred that they are the losers in the Hereafter. 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
