Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Ma'rif that he says: I saw Hazrat Umar bin Abdul Aziz at the place of Arafah, delivering a sermon to the people, and he was wearing two green garments. May Allah have mercy on him, when he mentioned death, he said: It is a severe pain, but not like ordinary severe pains. It is a severe grief, but not like ordinary severe griefs.
