And now that We replace one message by another - since God is fully aware of what He bestows from on high, step by step - they [who deny the truth] are wont to say: "Thou but inventest it!" Nay, but most of them do not understand it! 101 Say (O Muhammad SAW) Ruh-ul-Qudus [Jibrael (Gabriel)] has brought it (the Quran) down from your Lord with truth, that it may make firm and strengthen (the Faith of) those who believe and as a guidance and glad tidings to those who have submitted (to Allah as 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 God will not guide those who will not believe in the signs of God; and theirs will be a painful punishment. 104 Only those fabricate lies concerning God who do not believe in the signs of God, and these 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 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 Those -- God has set a seal on their hearts, and their hearing, and their eyes, and those -- they are the heedless ones; 108 On the Day of Judgment they will certainly be lost. 109 ۞ Surely, your Lord will be forgiving and merciful towards those who migrated after persecution and strove hard for the cause of God and remained steadfast. 110
