Al-Matalib al-'Aliyah 3882 — The virtues of Umar bin al-Khattab

It is narrated from Sa'id bin al-Musayyib that a camel of the public treasury was injured (its leg was broken), so Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) slaughtered it. Then he invited some of the Companions of the Prophet (peace and blessings be upon him) (may Allah be pleased with them) to eat its meat. On this occasion Sayyiduna al-Abbas (may Allah be pleased with him) said to him: "Would that you did this (arranged such a meal) every day, so that we could sit with you and talk." Sayyiduna Umar (may Allah be pleased with him) said: "I will never do the like of it again. The truth is that two companions of mine (the Prophet, peace and blessings be upon him, and Sayyiduna Abu Bakr al-Siddiq, may Allah be pleased with him) have passed on before me who followed a particular path (of abstinence and contentment); so if I act otherwise than they did, I too will be taken along a path other than theirs."
The chain of this report is sahih (authentic), and Imam Ibn Abi Shaybah narrated it in al-Musannaf (34419).
