Why scholars tend to translate or interpret the word علم 'ilm Knowledge in (interpretation) tafsir of the Qur'an or sharh (explanation) of ahadith/Hadith as knowledge of fiqh, sunna etc.
Why knowledge seems only related with the religion, as if sciences like Maths, Physics, Medicine don't seem to come to mind.
I know Muslims should have at least basic knowledge of their religion (worshiping like prayer/fasting...), but is this the only reason?
