When We substitute one revelation for another,- and Allah knows best what He reveals (in stages),- they say, "Thou art but a forger": but most of them understand not. 101 Say: The holy Spirit hath delivered it from thy Lord with truth, that it may confirm (the faith of) those who believe, and as guidance and good tidings for those who have surrendered (to Allah). 102 And certainly We know that they say: Only a mortal teaches him. The tongue of him whom they reproach is barbarous, and this is 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 They alone invent lies who do not believe in the words of God, and they are liars. 105 Whosoever denies having once believed -- unless he is forced to do so while his heart enjoys the peace of faith -- and opens his mind to disbelief will suffer the wrath of God. Their punishment will be great, 106 This is because they prefer the life of this world to the Hereafter and because God does not guide those who deny the truth. 107 These are the ones whose hearts, ears, and eyes Allah has sealed; and they are the neglectful. 108 Assuredly in the Hereafter they are the losers. 109 ۞ Then, verily, thy Lord unto those who have emigrated after they had been tempted and have thereafter striven hard and endured, verily thy Lord thereafter is Forgiving, Merciful. 110
