Your subject thread was secularism and not what is deen.
Worldy developments do not need Abraham, any deen or secularism.
Chinese, Russian and Godless societies did great inspite of being secular in arts, cultre, sciences or human services.
Similarly all other religious regions did great in worldy matters and are doing well opposite of islamic regions who are totally dependent.
Western or communist scoieties rose to high development era when got rid of religious clutches.
You do not need religions, deen or what ever for worldy matters, you need it for self rising if interested. Religions or call it deen are just set of belief which do not provide bread or shelter. Non Islamic world is more honest and kind in daily life than islam followers, which are basic beliefs of deen islam.
