Musannaf Ibn Abi Shayba 28:18

Ibn Numayr narrated to us, he said: Fudayl ibn Ghazwan narrated to us, from Muhammad al-Rasibi, from Bishr ibn ‘Asim, who said: ‘Umar ibn al-Khattab wrote his covenant, then said: "I have no need for it, for I heard the Messenger of Allah (peace and blessings of Allah be upon him) say: 'The rulers will be brought on the Day of Resurrection and will stand on the edge of Hell. Whoever was obedient, Allah will take him with His right hand until He saves him, and whoever disobeyed Allah, the bridge will break under him into a valley of fire that blazes intensely.'" He said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "So ‘Umar sent for Abu Dharr and for Salman. He said to Abu Dharr: 'Did you hear this hadith from the Messenger of Allah (peace and blessings of Allah be upon him)?' He said: 'Yes, by Allah, and beyond that valley is another valley of fire.'" He said: And he asked Salman, but he disliked to inform him of anything. So ‘Umar said: "Who will take it with what is in it?" Abu Dharr said: "The one whose nose and eyes Allah has humiliated, and whose cheek He has split upon the ground."
