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 (Muhammad), say, "The Holy Spirit has brought the Quran from your Lord to you in all truth to strengthen the faith of the believers and to be a guide and glad news for the Muslims". 102 And assuredly We know that they say: it is only a human being who teacheth him. The speech of him unto whom they incline is foreign while this is Arabic speech plain. 103 God will not guide those who will not believe in the signs of God; and theirs will be a painful punishment. 104 It is those who believe not in the Signs of Allah, that forge falsehood: it is they who lie! 105 Whoever disbelieves in Allah after his belief... except for one who is forced [to renounce his religion] while his heart is secure in faith. But those who [willingly] open their breasts to disbelief, upon them is wrath from Allah, and for them is a great punishment; 106 That is because they preferred the worldly life over the Hereafter and that Allah does not guide the disbelieving people. 107 These are the ones whose hearts, ears, and eyes Allah has sealed; and they are the neglectful. 108 and in the life to come, they will surely be the losers. 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
