When We replace a message with another -- and God knows best what He reveals -- they say: "You have made it up;" yet most of them do not know. 101 Say: 'The Holy Spirit sent it down from thy Lord in truth, and to confirm those who believe, and to be a guidance and good tidings to those who surrender.' 102 We know that they say a mere mortal has taught it (the Quran) to him (Muhammad). The language of the person whom they think has taught it to him is not Arabic. This (the Quran) is in illustrious Arabic. 103 Those that believe not in the signs of God, God will not guide; there awaits them a painful chastisement. 104 Only those who do not believe in Allah’s signs attribute lies and fabrications; and they themselves are liars. 105 Whosoever denies having once believed -- unless he is forced to do so while his heart enjoys the peace of faith -- and opens his mind to disbelief will suffer the wrath of God. Their punishment will be great, 106 This is because the worldly life was dearer to them than the Hereafter; and because Allah does not guide such disbelieving people. 107 These are they upon whose hearts and hearing and sight Allah hath set a seal; and these! they are the negligent. 108 Without doubt, in the Hereafter they will perish. 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
