And when We exchange a verse in the place of another verse and God knows very well what He is sending down -- they say, 'Thou art a mere forger!' Nay, but the most of them have no knowledge. 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 believe not in the Signs of Allah,- Allah will not guide them, and theirs will be a grievous Penalty. 104 They only invent falsehood who do not believe in the verses of Allah, and it is those who are the liars. 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 all this, because they hold this world's life in greater esteem than the life to come, and because God does not bestow His guidance upon people who deny the truth. 107 God has sealed their hearts, ears and eyes and they are not aware of it. 108 They will surely be losers in the life to come, 109 ۞ Then indeed your Lord? to those who emigrated, after they were persecuted, and then strove and were patient, surely, your Lord is thereafter Forgiving, the Most Merciful. 110
