Musannaf Ibn Abi Shaybah 35106 — What they said on who is given first

The father of Ja'far (may Allah have mercy on him) said: When Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) decided to establish the registers (diwans), he sought the people's counsel and asked: "With whom should I begin?" Someone said: "Begin with yourself." He said: "No! Rather, I will begin with those who are closest in kinship to the Messenger of Allah (peace and blessings be upon him), and then those who are closest to him (peace and blessings be upon him) after them." So he began with them.
