Ma'mar bin Rashid معمر بن راشد · The Book of al-Bay'ah

"I came to the Messenger of Allah with my father on the day of the Conquest (of Makkah) and said: 'O Messenger of Allah, accept my father's pledge to emigrate.' The Messenger of Allah said: 'I will accept his pledge for Jihad, for the emigration (Hijrah) has ceased."'
