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: "Holy inspiration has brought it down from thy Sustainer by stages, setting forth the truth, so that it might give firmness unto those who have attained to faith, and provide guidance and a glad tiding unto all who have surrendered themselves to God." 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 God will not guide those who do not believe in His miracles. They will suffer 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 Any one who, after accepting faith in Allah, utters Unbelief,- except under compulsion, his heart remaining firm in Faith - but such as open their breast to Unbelief, on them is Wrath from Allah, and theirs will be a dreadful Penalty. 106 all this, because they hold this world's life in greater esteem than the life to come, and because God does not bestow His guidance upon people who deny the truth. 107 Those are the ones over whose hearts and hearing and vision Allah has sealed, and it is those who are the heedless. 108 No doubt they shall be losers in the Hereafter. 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
