Sidqi,bhai, "and many more issues do not exist today", LOL.
prophets stories: examples in their stories how to solve problems logically, intellectually, thoughtfully, eg Joseph and his resolving the famine issue with saving for future. applicable today.
Habbits: many still have the habit of denying the truth, FAKE NEWS, etc, still applicable today.
Wars: there is no place on earth that is not free from conflict so we need continuous legislation from universal principles to deal with this, applicable today
Tribes: USA v Russia v China v Korea, call them nations or call them tribes, problems still there, applicable today.
Womens rights; #metoo movement, how men need to treat women properly, decently, respectfully and how women need to behave in society, applicable today.
Is this up to your pay grade?
