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 (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 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 who disbelieve in the signs of Allah – Allah does not guide them, and for them is a punishment, most painful. 104 They only forge falsehood, who believe not in the signs of God, and those -- they are the liars. 105 No one verbally denounces his faith in God - unless he is forced - but his heart is confident about his faith. But those whose breasts have become open to disbelief will be subject to the wrath of God and will suffer a great torment. 106 that, because they have preferred the present life over the world to come, and that God guides not the people of the unbelievers. 107 Those -- God has set a seal on their hearts, and their hearing, and their eyes, and those -- they are the heedless ones; 108 without a doubt, in the world to come they will be the losers. 109 ۞ And surely your Lord will be Most Forgiving and Most Merciful towards those who left their homes after they were persecuted, and who thereafter struggled hard and remained constant. 110
