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 Say (O Muhammad SAW) Ruh-ul-Qudus [Jibrael (Gabriel)] has brought it (the Quran) down from your Lord with truth, that it may make firm and strengthen (the Faith of) those who believe and as a guidance and glad tidings to those who have submitted (to Allah as Muslims). 102 Indeed, We know what they say, "It is only a human being who imparts [all] this to him!" But the tongue of him to whom they point is foreign, whereas this is plain Arabic speech. 103 Indeed, those who do not believe in the verses of Allah - Allah will not guide them, and for them is a painful punishment. 104 Only they invent falsehood who believe not Allah's revelations, and (only) they are the liars. 105 Any one who, after accepting faith in Allah, utters Unbelief,- except under compulsion, his heart remaining firm in Faith - but such as open their breast to Unbelief, on them is Wrath from Allah, and theirs will be a dreadful Penalty. 106 That is because they preferred the worldly life over the Hereafter and that Allah does not guide the disbelieving people. 107 Those are the ones over whose hearts and hearing and vision Allah has sealed, and it is those who are the heedless. 108 So it occurred that they are the 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
