حَدَّثَنَا مُحَمَّدُ بْنُ دَاوُدَ، قَالَ حَدَّثَنَا عَمْرُو بْنُ عَوْنٍ، قَالَ حَدَّثَنَا هُشَيْمٌ، عَنْ مُوسَى بْنِ السَّائِبِ، عَنْ قَتَادَةَ، عَنِ الْحَسَنِ، عَنْ سَمُرَةَ، قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " الرَّجُلُ أَحَقُّ بِعَيْنِ مَالِهِ إِذَا وَجَدَهُ وَيَتْبَعُ الْبَائِعُ مَنْ بَاعَهُ " .
