Why Does Quran Emphasize So Much On Morality And Not On Physical Health
Sunnah has both literal meaning i.e. way of the Prophet and is also used as a technical term i.e. That part of religion which relates to rituals and Ibadah and has been transmitted through ijma and tawatur e.g. Salah/ namaz, Roza, Hajj, Zakat ec. Here I am referring to the first meaning, which is not independent religion, but uswa/seerah of the prophet which is based on religion. And Quran tells us the basic morality (e.g. being good to people) was given in the nature of a human being.
