The only reason for muslim lagging is that they have stopped natural evolution of life, culture and society.
They are living in 21st century but mentally they are in 6th century. This gap is making their minds locked and confused what to do.
They can't find the answer and they wont. For them every thing in present world is haram but they need them all.
Jawaid sahab wants to run world trade & banking in gold coins, people are worried about cirumcison, hijab, eyes gazing, tv, mortgage free housing which they cant find, women rolesin economy, quran hafiz kids to carry parents into jannah and million other desires and isssues. Thats the lagging.
God help them.
