What did Rafi' say to his son regarding his participation in the Badr battle instead of the 'Aqaba pledge given by the Prophet Muhammad (saw)?
 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."
