Allah (SWT) in some places in the Quran uses فعل and in other places uses عمل.
- فافعلوا ما تومرون
- اعملوا ما شئتم
Is there a difference between them linguistically or semantically that can give us more insight into the commands of Allah?
I once read somewhere in a tafseer, that فعل is like hearing and seeing (passive), عمل is like listening and watching (active). I can't find it though.
