It is narrated from Hazrat Ya'la (may Allah be pleased with him) that on the day of the conquest of Makkah, my father and I presented ourselves before the Prophet (peace and blessings be upon him). I said, "O Messenger of Allah! (peace and blessings be upon him) Please take the pledge of migration from my father." The Prophet (peace and blessings be upon him) said, "I take the pledge of jihad from him, because the obligation of migration has ended."
