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 We know very well that they say, 'Only a mortal is teaching him.' The speech of him at whom they hint is barbarous; and this is speech Arabic, manifest. 103 Those who believe not in the Signs of Allah,- Allah will not guide them, and theirs will be a grievous Penalty. 104 It is only those who believe not in the signs of Allah who fabricate lie, and those! they are the 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 loved the life of the world above the Hereafter, and because Allah guideth not an infidel people. 107 They are those whose hearts, hearing and sight are sealed by Allah; they are the heedless. 108 No doubt they shall be losers in the Hereafter. 109 ۞ And yet, behold, thy Sustainer [grants His forgiveness] unto those who forsake the domain of evil after having succumbed to its temptation, and who thenceforth strive hard [in God's cause] and are patient in adversity: behold, after such [repentance] thy Sustainer is indeed much-forgiving, a dispenser of grace! 110
