When We exchange a verse for another and Allah knows best what He is sending down they say: 'You are but a forger' No, most of them do not know. 101 Tell them: "It is the spirit of holiness that has brought it down, by stages, from your Lord so that it might bring firmness to those who believe, and guidance to the Right Way, and give glad tidings of felicity and success to those who submit to Allah." 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 Verily, as for those who will not believe in God's messages, God does not guide them aright; and grievous suffering will be their lot [in the life to come]. 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 Those are the ones over whose hearts and hearing and vision Allah has sealed, and it is those who are the heedless. 108 They will surely be losers in the life to come, 109 ۞ Then, verily, thy Lord unto those who have emigrated after they had been tempted and have thereafter striven hard and endured, verily thy Lord thereafter is Forgiving, Merciful. 110
