When God replaces one revelation with another, He knows best what to reveal. But they say, "(Muhammad), you have falsely invented it." Most people are ignorant. 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 We know very well that they say: 'A mortal teaches him' The tongue of him at whom they hint is a nonArab; and this is a clear Arabic tongue. 103 Those who believe not in the Signs of Allah,- Allah will not guide them, and theirs will be a grievous Penalty. 104 They only forge falsehood, who believe not in the signs of God, and those -- they are the liars. 105 Whosoever disbelieves in Allah after believing except he who is forced while his heart remains in his belief but he who opens his chest for disbelief, shall receive the Anger of Allah and for such awaits a mighty punishment. 106 That is because they preferred the worldly life over the Hereafter and that Allah does not guide the disbelieving people. 107 They are those whose hearts, hearing and sight are sealed by Allah; they are the heedless. 108 and in the life to come, they will surely be the losers. 109 ۞ And yet, behold, thy Sustainer [grants His forgiveness] unto those who forsake the domain of evil after having succumbed to its temptation, and who thenceforth strive hard [in God's cause] and are patient in adversity: behold, after such [repentance] thy Sustainer is indeed much-forgiving, a dispenser of grace! 110
