You mean, what if a Muslim changed the words in the Bible? Like say:
“There is neither Gentile or Jew, woman or man, slave or free, for in Christ all are one.” (my paraphrase)
To
“There is neither unbeliever or Muslim, woman or man, slave or free, for in Allah all are one.”
Like that?
Not exactly. “There is neither Muslim, or Christian, woman or man, slave or free, for in God all are one.”
Now contrast the reaction of a Christian to that with what the likely reaction of a Muslim if the Bible said something like:
"And slay them wherever ye find them, and drive them out of the places whence they drove you out, for persecution [of Christians and Jews] is worse than slaughter [of Muslims]…and wage Crusades against them until persecution is no more, and religion is for the Holy Trinity.
"Soon shall We cast terror into the hearts of Muslims, for that they joined companions with God, for which He had sent no authority.
"Let those wage Crusades in the way of the Holy Trinity [all glory and praise] who sell the life of this world for the other. Whoso fighteth in the way of the Holy Trinity [all glory and praise], be he slain or be he victorious, on him We shall bestow a vast reward.
Those who believe fight in the cause of the Father [blessed be His Holy Name], Son [blessed be his Sacred Heart], and Holy Spirit [come, fill our hearts].
"The punishment of those who wage war against the Holy Trinity [all glory and praise] and strive to make mischief in the land is only this, that they should be murdered or crucified or their hands and their feet should be cut off on opposite sides or they should be imprisoned; this shall be as a disgrace for them in this world, and in the hereafter they shall have a grievous chastisement.
I will cast terror into the hearts of those who disbelieve [in the Holy Trinity]. Therefore strike off their heads and strike off every fingertip of them.
"And wage Crusades against them until there is no more persecution and religion should be only for the Holy Trinity [all glory and praise].
"So when the Holy Season has passed away, then slay the idolaters wherever you find them, and take them captives and besiege them and lie in wait for them in every ambush, then if they repent and keep up prayer and pay the poor-rate, leave their way free to them.
"Wage Crusades against them, God the Father [blessed be His Holy Name] will punish them by your hands and bring them to disgrace. "… etc.
The whole point is we have the context of the Koran correct.
