When We replace a message with another -- and God knows best what He reveals -- they say: "You have made it up;" yet most of them do not know. 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 God will not guide those who will not believe in the signs of God; and theirs will be a painful punishment. 104 Only those fabricate lies concerning God who do not believe in the signs of God, and these are the liars. 105 No one verbally denounces his faith in God - unless he is forced - but his heart is confident about his faith. But those whose breasts have become open to disbelief will be subject to the wrath of God and will suffer a great torment. 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 whose hearts and whose hearing and whose sight God has sealed - it is they, they who are heedless! 108 Undoubtedly they in the Hereafter shall be the very losers. 109 ۞ And surely your Lord will be Most Forgiving and Most Merciful towards those who left their homes after they were persecuted, and who thereafter struggled hard and remained constant. 110
