Sayyiduna Muawiyah bin Qurrah narrates from his father: I came to the Prophet (ﷺ) with a group from the tribe of Muzaynah. We pledged allegiance to the Prophet (ﷺ). At that time, the buttons of his shirt were open. After the pledge, with the Prophet’s (ﷺ) permission, I put my hand inside his blessed shirt and touched and felt the Seal of Prophethood. The narrator of the hadith, Urwah, says: Whenever I saw Muawiyah and his son, whether in winter or summer, I always saw the buttons of their shirts open; they would never fasten them.
