Musannaf Ibn Abi Shayba 3:3135

Abu Mu'awiyah narrated to us, from al-A'mash, from Mujahid, from Abdullah ibn Damrah, from Ka'b, who said: The sun does not rise on a day that is greater than Friday. When it rises, everything is terrified of it, except for the two heavy ones (mankind and jinn) upon whom is the reckoning and the punishment.
