عَنْ زَيْدِ بْنِ خَالِدٍ الْجُهَنِيِّ، أَنّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ سُئِلَ عَنِ اللُّقَطَةِ، فَقَالَ: عَرِّفْهَا سَنَةً فَإِنْ جَاءَ بَاغِيهَا فَأَدِّهَا إِلَيْهِ، وَإِلَّا فَاعْرِفْ عِفَاصَهَا وَوِكَاءَهَا ثُمَّ كُلْهَا فَإِنْ جَاءَ بَاغِيهَا فَأَدِّهَا إِلَيْهِ(ابو داؤد: ۱۷۰۶)
Translation
Hazrat Zaid bin Khalid al-Juhani (may Allah be pleased with him) narrated that the Messenger of Allah (PBUH) was asked about lost property, so He said: "Announce it for one year. If its seeker comes, give it to him; otherwise, keep in mind its pouch (or container) and its fastening string, then eat it (use it for yourself). After that, if its seeker comes, hand it over to him."
