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 thou: the Holy Spirit hath brought it down from thy Lord with truth, that it may establish those who believe, and as a guidance and glad tidings unto the Muslims. 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 (As for) those who do not believe in Allah's communications, surely Allah will not guide them, and they shall have a painful punishment. 104 They only invent falsehood who do not believe in the verses of Allah, and it is those who are the 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 loved and preferred the life of this world over that of the Hereafter. And Allah guides not the people who disbelieve. 107 Those are they whose hearts, ears, and eyes Allah has sealed up, and they take no heed. 108 without a doubt, in the world to come they will be the losers. 109 ۞ Then, verily! Your Lord for those who emigrated after they had been put to trials and thereafter strove hard and fought (for the Cause of Allah) and were patient, verily, your Lord afterward is, Oft-Forgiving, Most Merciful. 110
