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: The Holy spirit has revealed it from your Lord with the truth, that it may establish those who believe and as a guidance and good news for those who submit. 102 We know that they say a mere mortal has taught it (the Quran) to him (Muhammad). The language of the person whom they think has taught it to him is not Arabic. This (the Quran) is in illustrious Arabic. 103 Those that believe not in the signs of God, God will not guide; there awaits them a painful chastisement. 104 Only those fabricate lies concerning God who do not believe in the signs of God, and these are the liars. 105 Whoso disbelieveth in Allah after his belief - save him who is forced thereto and whose heart is still content with the Faith - but whoso findeth ease in disbelief: On them is wrath from Allah. Theirs will be an awful doom. 106 This is because the worldly life was dearer to them than the Hereafter; and because Allah does not guide such disbelieving people. 107 Such are they whose hearts and ears and eyes Allah hath sealed. And such 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
