Musannaf Ibn Abi Shayba 16:471

Abu Bakr narrated to us, he said: Waki’ narrated to us, from al-Hakam ibn ‘Atiyyah, from al-Nadr ibn ‘Abd Allah, that Qays ibn ‘Abbad went as a delegate to Mu’awiyah. He (Mu’awiyah) clothed him in a *raytah* (a soft, single-piece garment). He (Qays) ripped its border and wore it as a shawl.
