Musannaf Ibn Abi Shaybah

Hazrat Ja'far, may Allah have mercy on him, narrates from his father that when Hazrat Umar bin Khattab, may Allah be pleased with him, decided to establish the register (diwan), he, may Allah be pleased with him, sought advice from the people and asked: "With whom should I begin?" Someone said: "Begin with yourself." He, may Allah be pleased with him, said: "No! Rather, I will begin with those who are closer in relation to the Messenger of Allah, peace and blessings be upon him, and then those who are next closest to him, peace and blessings be upon him." Thus, he, may Allah be pleased with him, began with them.
