Chapter on Lost Property and Stray Animals
Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 2|Chapter 30
وَ رُوِيَ عَنْ حَنَانِ بْنِ سَدِيرٍ قَالَ: سَأَلَ رَجُلٌ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ عَنِ اَللُّقَطَةِ وَ أَنَا أَسْمَعُ فَقَالَ "تُعَرِّفُهَا سَنَةً فَإِنْ وَجَدْتَ صَاحِبَهَا وَ إِلاَّ فَأَنْتَ أَحَقُّ بِهَا".
It is narrated from Hanan ibn Sadir, who said: A man asked Abu Abdullah عليه السلام about lost property while I was listening. Imam عليه السلام said: "Announce it for one year. If you find its owner, return it to him; otherwise, you are more entitled to keep it."
