Muslims brag that the Quran is preserved in heaven and Allah has preserved it on earth. They brag about the translation perfection and brag about the Quran being the only undoctored book that has transcended time.
Unfortunately, most of the people who say these are not properly informed that the Muslims living in the west have dropped that slogan and stopped beating their chest of having the very Quran that Jubril gave to Mohammed.
That argument has been reduced to faeces. Now, there are currently 37 different Qurans found in the Arabic language, not translated. These date back many years ago. It has since shattered the Islamic cleric community. Yet, some uninformed African Muslims are not up to date with the implosion going on in the Muslim world in the west. They continue to spew the pulverize argument that there is only ONE QURAN.
Time's up! The incongruity and lackluster differences in the narrative is described as STANDARD HOLES according to one Islamic Cleric Qadhi.
For reference, kindly search "the standard narrative has holes in it" by Yasir Qadhi.
The timelines in the standard narratives do not match. So much is going on. I did my research years ago on Islam but these guys are way ahead of me.
