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 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 It is those who believe not in the Signs of Allah, that forge falsehood: it is they who lie! 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 That is because they loved the life of the world above the Hereafter, and because Allah guideth not an infidel people. 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 ۞ And yet, behold, thy Sustainer [grants His forgiveness] unto those who forsake the domain of evil after having succumbed to its temptation, and who thenceforth strive hard [in God's cause] and are patient in adversity: behold, after such [repentance] thy Sustainer is indeed much-forgiving, a dispenser of grace! 110
