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 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 Those who disbelieve in the signs of Allah – Allah does not guide them, and for them is a punishment, most painful. 104 Only those who do not believe in Allah’s signs attribute lies and fabrications; and they themselves are liars. 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 They are the ones whose hearts and ears and eyes have been sealed by God; and these are the heedless. 108 On the Day of Judgment they will certainly be lost. 109 ۞ Then, verily! Your Lord for those who emigrated after they had been put to trials and thereafter strove hard and fought (for the Cause of Allah) and were patient, verily, your Lord afterward is, Oft-Forgiving, Most Merciful. 110
