It is narrated from Sayyiduna Qarah (may Allah be pleased with him), he says: I presented myself before the Messenger of Allah (peace and blessings be upon him) along with a delegation from Banu Muzaynah and we pledged allegiance to him. The buttons of the Prophet’s (peace and blessings be upon him) shirt were open. When we had pledged allegiance, I put my hand inside the Prophet’s (peace and blessings be upon him) shirt and touched the Seal of Prophethood. ‘Urwah says: I saw Mu‘awiyah and his son Iyas in both cold and hot weather, that they always kept the buttons of their shirts open and never closed them.
