When We substitute one revelation for another, and God knows best what He reveals, they say, "You are but a fabricator." Indeed, most of them have no knowledge. 101 (Muhammad), say, "The Holy Spirit has brought the Quran from your Lord to you in all truth to strengthen the faith of the believers and to be a guide and glad news for the Muslims". 102 We know very well that they say: 'A mortal teaches him' The tongue of him at whom they hint is a nonArab; and this is a clear Arabic tongue. 103 Verily those who believe not in the signs of Allah - Allah shall not guide them, and unto them shall be a torment afflictive. 104 It is but they who will not believe in God's messages that invent this falsehood; and it is they, they who are lying! 105 He who disbelieves in Allah after his having believed, not he who is compelled while his heart is at rest on account of faith, but he who opens (his) breast to disbelief-- on these is the wrath of Allah, and they shall have a grievous chastisement. 106 that, because they have preferred the present life over the world to come, and that God guides not the people of the unbelievers. 107 They are those whose hearts, hearing and sight are sealed by Allah; they are the heedless. 108 No doubt, in the Hereafter, they will be the losers. 109 ۞ Then, surely thy Lord -- unto those who have emigrated after persecution, then struggled and were patient -- surely thy Lord thereafter is All-forgiving, All-compassionate. 110
