Chapter 64: Military Expeditions led by the Prophet (pbuh) (Al-Maghaazi)
Narrated Mu 'adh bin Rifa 'a bin Rafi ': Rifa 'a was one of the warriors of Badr while (his father) Rafi 'was one of the people of Al-' Aqaba
(i. e. those who gave the pledge of allegiance at Al-' Aqaba). Rafi 'used to say to his son, "I would not
have been happier if I had taken part in the Badr battle instead of taking part in the 'Aqaba pledge."
