When We replace a message with another -- and God knows best what He reveals -- they say: "You have made it up;" yet most of them do not know. 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 And We certainly know that they say, "It is only a human being who teaches the Prophet." The tongue of the one they refer to is foreign, and this Qur'an is [in] a clear Arabic language. 103 Those who disbelieve in the signs of Allah – Allah does not guide them, and for them is a punishment, most painful. 104 It is but they who will not believe in God's messages that invent this falsehood; and it is they, they who are lying! 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 That is because they loved and preferred the life of this world over that of the Hereafter. And Allah guides not the people who disbelieve. 107 These are they upon whose hearts and hearing and sight Allah hath set a seal; and these! they are the negligent. 108 Undoubtedly they in the Hereafter shall be the very losers. 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
