You may despise it but these are the facts, Muhammad (pbuh), Umar (ra), Hamza (ra), Khalid bin walid (ra) were well known for being big, muscular and strong. After all they were not only leaders in politics or spiritually but physically. Remmeber they did not coward when battles happened but were at the front of battles. Hamza was martyrd in battle. Khalid as a muslim general never lost a single battle.
I don't think that "facts
means what you think it means.
you see we literally have everything described for us in Islam
What a sad, sad life it must be to live based on an instruction manual that describes and proscribes everything for you...
