The deputation of the Ansar to the Prophet (ﷺ) at Makkah, and the Al-Aqaba
حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا سُفْيَانُ، قَالَ كَانَ عَمْرٌو يَقُولُ سَمِعْتُ جَابِرَ بْنَ عَبْدِ اللَّهِ ـ رضى الله عنهما ـ يَقُولُ شَهِدَ بِي خَالاَىَ الْعَقَبَةَ. قَالَ أَبُو عَبْدِ اللَّهِ قَالَ ابْنُ عُيَيْنَةَ أَحَدُهُمَا الْبَرَاءُ بْنُ مَعْرُورٍ.
Narrated Jabir bin `Abdullah: I was present with my two maternal uncles at Al-`Aqaba (where the pledge of allegiance was given). (Ibn 'Uyaina said, "One of the two was Al-Bara' bin Marur.")
