My bro talking about the concept of modernization in Islam, being muslim if we are unable to understand a little fact then it is shameful for us.
I don't know about the ideolies of al-qaeeda, taliban etc but something that i know is enough to make you understand about Islam.
That is, Islam is what that it was 1400 years ago & will be like that until the world ends, there is no modernization concept in Islam, Islam is flexible within itself, it is not flexible so you should bring changes in it of your own, it isn't written anywhere in Quran pak or Hadees mubarak that you people are allowed to bring changes in Islam as era changes.
