Why Does Quran Emphasize So Much On Morality And Not On Physical Health
I do not understand what you are saying. You are simply saying that ethics is about our preparation for the Hereafter. But my common sense says that I should be morally good Then why does the Qur’an emphasize this so much?
The Qur’an has left many other aspects to our intellect, then the Qur’an could have left this decision to our intellect.
Being kind to people is common sense based on our nature and Prophet Muhammad (SwS) emphasized it both through his words and through his Uswa (Seerah). It can also be called Sunnah in literal sense as in way of the Prophet (sws).
