When We exchange a verse for another and Allah knows best what He is sending down they say: 'You are but a forger' No, most of them do not know. 101 Say: The holy Spirit hath delivered it from thy Lord with truth, that it may confirm (the faith of) those who believe, and as guidance and good tidings for those who have surrendered (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 Only they forge the lie who do not believe in Allah's communications, and these 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 This is because the worldly life was dearer to them than the Hereafter; and because Allah does not guide such disbelieving people. 107 Those -- God has set a seal on their hearts, and their hearing, and their eyes, and those -- they are the heedless ones; 108 and in the life to come, they will surely be the 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
