When We exchange a verse for another and Allah knows best what He is sending down they say: 'You are but a forger' No, most of them do not know. 101 Say (O Muhammad SAW) Ruh-ul-Qudus [Jibrael (Gabriel)] has brought it (the Quran) down from your Lord with truth, that it may make firm and strengthen (the Faith of) those who believe and as a guidance and glad tidings to those who have submitted (to Allah as 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 Verily, as for those who will not believe in God's messages, God does not guide them aright; and grievous suffering will be their lot [in the life to come]. 104 They only forge falsehood, who believe not in the signs of God, and those -- they are the liars. 105 As for anyone who denies God after having once attained to faith - and this, to be sure, does not apply to one who does it under duress, the while his heart remains true to his faith, but [only, to] him who willingly opens up his heart to a denial of the truth: upon all such [falls] God's condemnation, and tremendous suffering awaits them: 106 This is because they have given preference to this life over the life to come and God does not guide 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 a doubt, in the world to come they will be the losers. 109 ۞ Those who left their homes for the cause of God after they had been persecuted, strove hard for His cause and exercised patience should know (even though they had verbally renounced their faith) that your Lord is All-forgiving and All-merciful. 110
