Narrated by:Quza'a
Narrated Quza'a:I heard Abu Said saying four words. He said, "I heard the Prophet (ﷺ) (saying the following narrative)." He had participated in twelve holy battles with the Prophet.
حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، حَدَّثَنَا شُعْبَةُ، قَالَ أَخْبَرَنِي عَبْدُ الْمَلِكِ بْنُ عُمَيْرٍ، عَنْ قَزَعَةَ، قَالَ سَمِعْتُ أَبَا سَعِيدٍ ـ رضى الله عنه ـ أَرْبَعًا قَالَ سَمِعْتُ مِنَ النَّبِيِّ، صلى الله عليه وسلم وَكَانَ غَزَا مَعَ النَّبِيِّ صلى الله عليه وسلم ثِنْتَىْ عَشْرَةَ غَزْوَةً ح.
