Eye opener for "Muslim Ummah"

So, why is Germany still a great power and the Ottoman Empire crumbled?

Ottoman empire does not represent all the regions that were colonized. The Caliphs and company of the ‘empire’ indulged in similar luxuries as the ‘kings’ and ‘ameers’ of oil rich middle eastern countries today. You cannot promote music and poetry and claim to be strong.

I agree with the article you quoted that muslim scientists contributed a lot during the ‘dark ages’ in Europe but neglected science as they became militarily strong in Asia and Africa.
