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, [O Muhammad], "The Pure Spirit has brought it down from your Lord in truth to make firm those who believe and as guidance and good tidings to the Muslims." 102 And indeed We know that they (polytheists and pagans) say: "It is only a human being who teaches him (Muhammad SAW)." The tongue of the man they refer to is foreign, while this (the Quran) is a clear Arabic tongue. 103 Those who disbelieve in the verses of Allah, Allah does not guide them for them is a painful punishment. 104 They only forge falsehood, who believe not in the signs of God, and those -- they 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 Such are they whose hearts and ears and eyes Allah hath sealed. And such are the heedless. 108 So it occurred that they are the losers in the Hereafter. 109 ۞ Then, verily! Your Lord for those who emigrated after they had been put to trials and thereafter strove hard and fought (for the Cause of Allah) and were patient, verily, your Lord afterward is, Oft-Forgiving, Most Merciful. 110
