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 brought the revelation from thy Lord in Truth, in order to strengthen those who believe, and as a Guide and Glad Tidings to Muslims. 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 Indeed, those who do not believe in the verses of Allah - Allah will not guide them, and for them is a painful punishment. 104 It is only those who believe not in the Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) of Allah, who fabricate falsehood, and it is they who are liars. 105 Whosoever disbelieveth in Allah after his belief - save him who is constrained and his heart is at rest with the belief - but whosoever expandeth his breast to infidelity, upon them shall be wrath from Allah, and unto them shall be a torment mighty. 106 That is because they have chosen the life of the world rather than the Hereafter, and because Allah guideth not the disbelieving folk. 107 They are those upon whose hearts, hearing (ears) and sight (eyes) Allah has set a seal. And they are the heedless! 108 They will surely be losers in the life to come, 109 ۞ Surely, your Lord will be forgiving and merciful towards those who migrated after persecution and strove hard for the cause of God and remained steadfast. 110
