salaam,
I just watched the first few minutes, but seem not good.
How one can expect ruins of large rock/clay buildings and cities from an ancient ‘islamic city’?, when they had lead a simple life!. Qur’an repeatedly mentions such large buildings and structures were made by transgressors/disbelievers/ignorant people! (eg: 15:78-83, 89:6-14).
They say “it was an agricultural city” but “to date there is no record of trees having ever existed in ancient Mecca”
From the Qur’an:
"Our Lord, that I resided/inhabited from my descendants at a valley of no plants/crops at Your House/bayt, the Forbidden/Restricted/Sacred- 14:37
They also say things which are not in the Qur’an, i.e. from traditional sources (e.g. about Prophet Muhammad’s father, grandfather, wife’s name, wife was a merchant etc.)
I think it’s not worth watching for a Qur’anic muslim.
