Sufyan bin Wahb Khawlani (may Allah have mercy on him) says that when we conquered the land of Egypt by the sword, Sayyiduna Zubair (may Allah be pleased with him) said to Sayyiduna Amr bin Al-Aas (may Allah be pleased with him)—who was the conqueror of Egypt and the commander of the Muslim army—"O Amr bin Al-Aas! Distribute it." He replied, "I will not distribute it yet." Sayyiduna Zubair (may Allah be pleased with him) swore an oath and said, "You will have to distribute it just as the Prophet (peace and blessings be upon him) distributed Khaybar." He said, "I cannot distribute it before corresponding with the Commander of the Faithful." So they wrote a letter of this nature to Sayyiduna Umar (may Allah be pleased with him), and the reply came from there: "Keep it as it is (leave it as it is) until the next generation participates in the battle."
