Musannaf Ibn Abi Shayba 33:858

Abu Mu’awiyah narrated to us, from Mutarrif, who said: I saw Umar ibn Abd al-Aziz addressing the people at Arafat, and he was wearing two green garments. He mentioned death and said: "A choking that is not like [any other] choking, and a suppression that is not like [any other] suppression."
