islam since the ottoman empire has turned from a religion of heroism to worshipping old meek people no matter what. i am asking if that is sustainable and especially after all the useless boomers die off since they were the (almost) last generation to be traditionally teached the qur'an. and there is also the question of how islam would sustain itself under modernity since many people are only muslims in name only.
Bit of a subjective question,
but to answer your question, there are hundreds of millions of Muslims today that have memorised the Quran. If the Quran were to disappear today, there would be millions of copies distributed within days. Know in regard to the question of Islam being the Fastest Growing religion, if you head over to the Pew research website, you’ll realise that it’s due to conversion rate and not birth rate.
It’s seems like you have an issue with Islam, if you are been sincere in your questioning, then there are other avenues you could take, which would easily give you the answers you seek. By making this ignorant post you do come across as a spiteful and hateful individual who enjoys creating hate and discord to and against Muslims, which I hope is not the case (my opinion on reading your post).
