Hazrat Muawiyah bin Qurrah narrates from his father, who says: I presented myself before the Noble Prophet Muhammad (peace and blessings be upon him) and pledged allegiance to him, and (at that time) the blessed shirt of the Prophet (peace be upon him) was open (i.e., the buttons were undone). Hazrat Urwah says: Thus, I saw Hazrat Muawiyah and his son in both cold and hot weather with their buttons undone.
