What is quranic guidance on international mortgages, Trade on LC system, crop buying of entire country's for next five years, oil spillage in seas, oceans pollution, global warming, human trafficking, drug trafficking, women flying jets, women flying space ships, space laws, copy rights, blah, blah, blah ......and million problems.
I will give you a break here.
Quranic guidance was mostly applicable for the time it came in, since wild tribes needed to be straighten. but there are few laws applicable for future too, but need to be adjusted like interest or 80 lashes etc. Now we have prisons etc or forced social services as example.
Human society have to go forward according to current issues. In year 5118 today's laws wont exist same as year 1018 laws do not exist today, like slavery, beheading or hand cutting etc.
Why muslim are lagging, thanks to traditional or modern mullah, because they want to live in year 600 of the prophet's era like 4 wives or keep sitting in mosques but its not working, a muslim or jew software engineer can not leave his post for prayers if he is working on a projects with a team sitting in many countries at the same time. through virtual connections. slowly he will be out of habit and will change into just a name muslim.
I understand and respect that you are a quran only scholar, but you are in 2018 and your kids will be in 2118, they wont have your convictions.
Sooner or later all religions will disappear, only knowledge of God's existence will remain.
