Jami` at-Tirmidhi, Hadith 1373 ⓘ
Zaid bin Khalid Al-Juhni narrated that the Messenger of Allah was asked about the lost item. He said: "Make a public announcement about it for one year, if it is claimed then give it to him. Otherwise remember its sack, string, and its count. Then use it, and if its owner comes, give it to him."
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا أَبُو بَكْرٍ الْحَنَفِيُّ، أَخْبَرَنَا الضَّحَّاكُ بْنُ عُثْمَانَ، حَدَّثَنِي سَالِمٌ أَبُو النَّضْرِ، عَنْ بُسْرِ بْنِ سَعِيدٍ، عَنْ زَيْدِ بْنِ خَالِدٍ الْجُهَنِيِّ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم سُئِلَ عَنِ اللُّقَطَةِ فَقَالَ " عَرِّفْهَا سَنَةً فَإِنِ اعْتُرِفَتْ فَأَدِّهَا وَإِلاَّ فَاعْرِفْ وِعَاءَهَا وَعِفَاصَهَا وَوِكَاءَهَا وَعَدَدَهَا ثُمَّ كُلْهَا فَإِذَا جَاءَ صَاحِبُهَا فَأَدِّهَا " . قَالَ أَبُو عِيسَى حَدِيثُ زَيْدِ بْنِ خَالِدٍ حَدِيثٌ حَسَنٌ صَحِيحٌ غَرِيبٌ مِنْ هَذَا الْوَجْهِ . قَالَ أَحْمَدُ أَصَحُّ شَيْءٍ فِي هَذَا الْبَابِ هَذَا الْحَدِيثُ .
