أحمد:٢٠٢٠٢حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ أَخْبَرَنَا الْحَجَّاجُ بْنُ أَرْطَأَةَ عَنْ سَعِيدِ بْنِ زَيْدِ بْنِ عُقْبَةَ عَنْ أَبِيهِ عَنْ سَمُرَةَ بْنِ جُنْدُبٍ قَالَ

قَالَ رَسُولُ اللهِ ﷺ مَنْ أَصَابَ مَتَاعَهُ بِعَيْنِهِ فَهُوَ أَحَقُّ بِهِ وَيَتْبَعُ صَاحِبُهُ مَنْ اشْتَرَاهُ مِنْهُ وَقَالَ يَزِيدُ مَرَّةً مَنْ وَجَدَ مَتَاعَهُ
