Abu Uthman Nahdi and from him Mujashi' bin Mas'ud (may Allah be pleased with him) narrated that I took (my brother Abu Ma'bad, may Allah be pleased with him) to the service of the Prophet (peace and blessings of Allah be upon him) to pledge allegiance to him for migration. The Prophet (peace and blessings of Allah be upon him) said that the reward for migration has ended along with those who migrated. However, I take his pledge for Islam and Jihad. Abu Uthman said that then I met Abu Ma'bad (may Allah be pleased with him) and asked him about this, so he said that Mujashi' (may Allah be pleased with him) has narrated correctly.
