Majma al-Zawaid — Hadith 9768

Sayyiduna Sufyan bin Wahb al-Khawlani (may Allah be pleased with him) narrates: When we conquered Egypt without any treaty, Sayyiduna Zubayr bin al-Awwam (may Allah be pleased with him) stood up and said: O Sayyiduna Amr bin al-As (may Allah be pleased with him), divide it (that is, its land among the fighters). Sayyiduna Amr (may Allah be pleased with him) said: I will not divide it. Sayyiduna Zubayr (may Allah be pleased with him) said: By Allah! You will certainly divide it, just as the Messenger of Allah (peace and blessings be upon him) divided (the land of) Khaybar. Sayyiduna Amr (may Allah be pleased with him) said: By Allah! I will not divide it until I write (about it) to the Commander of the Faithful. Then he wrote to Sayyiduna Umar (may Allah be pleased with him), and Sayyiduna Umar (may Allah be pleased with him) wrote back to him: Leave it as it is, so that generation after generation may go out on campaigns from it.
