It is narrated from Sayyiduna Mujashi' bin Mas'ud al-Sulami (may Allah be pleased with him) that he came to the Messenger of Allah (peace and blessings be upon him) on the day of the Conquest of Makkah and said: O Messenger of Allah! This is my brother Mujalid bin Mas'ud; take his pledge of allegiance for emigration (hijrah). He (peace and blessings be upon him) said: "There is no emigration after the Conquest of Makkah, but I will take his pledge for Islam."
