Sa'eed bin Hani' said:"I heard 'Irbad bin Sariyah say: 'I was with the Prophet (ﷺ) and a Bedouin said: "Pay me back for my young camel, and he gave him an older (i.e., better) camel." He said: 'O Messenger of Allah! It is older (i.e., better) than my camel.' The Messenger of Allah (ﷺ) said: 'The best of people are those who are best in repaying."'
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا زَيْدُ بْنُ الْحُبَابِ، حَدَّثَنَا مُعَاوِيَةُ بْنُ صَالِحٍ، حَدَّثَنِي سَعِيدُ بْنُ هَانِئٍ، قَالَ سَمِعْتُ الْعِرْبَاضَ بْنَ سَارِيَةَ، يَقُولُ كُنْتُ عِنْدَ النَّبِيِّ ـ صلى الله عليه وسلم ـ فَقَالَ أَعْرَابِيٌّ اقْضِنِي بَكْرِي . فَأَعْطَاهُ بَعِيرًا مُسِنًّا فَقَالَ الأَعْرَابِيُّ يَا رَسُولَ اللَّهِ هَذَا أَسَنُّ مِنْ بَعِيرِي . فَقَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " خَيْرُ النَّاسِ خَيْرُهُمْ قَضَاءً " .
