Why are muslims backward?

[Timotheus]

because they are not real muslims, look at the Time before Hadith, The muslim ummah was great

[Osman]

I have been denying the fact that Muslims are behind other nations by trying to justify their condition using colonization as an excuse. Lately, I have come to think that something is wrong with muslim mind. I need a better understanding on the reasons of muslim backwardness.

It's hard for societies to advance when they've been bombed to smithereens for the worst part of a century.
