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 thou: the Holy Spirit hath brought it down from thy Lord with truth, that it may establish those who believe, and as a guidance and glad tidings unto the Muslims. 102 And certainly We know that they say: Only a mortal teaches him. The tongue of him whom they reproach is barbarous, and this is clear Arabic tongue. 103 Those who do not believe in the words of God are verily not guided by God. For them is severe punishment. 104 It is those who believe not in the Signs of Allah, that forge falsehood: it is they who lie! 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 they love this world's life more than the hereafter, and because Allah does not guide the unbelieving people. 107 They are those whose hearts, hearing and sight are sealed by Allah; they are the heedless. 108 No doubt they shall be losers in the Hereafter. 109 ۞ But verily thy Lord,- to those who leave their homes after trials and persecutions,- and who thereafter strive and fight for the faith and patiently persevere,- Thy Lord, after all this is oft-forgiving, Most Merciful. 110
