Sahih al-Bukhari 3993
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."
حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، حَدَّثَنَا حَمَّادٌ، عَنْ يَحْيَى، عَنْ مُعَاذِ بْنِ رِفَاعَةَ بْنِ رَافِعٍ،، وَكَانَ، رِفَاعَةُ مِنْ أَهْلِ بَدْرٍ، وَكَانَ رَافِعٌ مِنْ أَهْلِ الْعَقَبَةِ، فَكَانَ يَقُولُ لاِبْنِهِ مَا يَسُرُّنِي أَنِّي شَهِدْتُ بَدْرًا بِالْعَقَبَةِ قَالَ سَأَلَ جِبْرِيلُ النَّبِيَّ صلى الله عليه وسلم‏.‏ بِهَذَا‏.‏
