Sunan Abi Dawud 1707
The aforesaid tradition has also been transmitted by Zaid bin Khalid al-Juhani through a different chain of narrators. This version has:
The Messenger of Allah (SWAS) was asked about a find.  He replied : Make the matter known for a year; if its owner comes, give it to him, otherwise note its string and its container and have it along with your property.  If its owner comes, deliver it to him.
حَدَّثَنَا أَحْمَدُ بْنُ حَفْصٍ، حَدَّثَنِي أَبِي، حَدَّثَنِي إِبْرَاهِيمُ بْنُ طَهْمَانَ، عَنْ عَبَّادِ بْنِ إِسْحَاقَ، عَنْ عَبْدِ اللَّهِ بْنِ يَزِيدَ، عَنْ أَبِيهِ، يَزِيدَ مَوْلَى الْمُنْبَعِثِ عَنْ زَيْدِ بْنِ خَالِدٍ الْجُهَنِيِّ، أَنَّهُ قَالَ سُئِلَ رَسُولُ اللَّهِ صلى الله عليه وسلم فَذَكَرَ نَحْوَ حَدِيثِ رَبِيعَةَ ‏.‏ قَالَ وَسُئِلَ عَنِ اللُّقَطَةِ فَقَالَ ‏
"‏ تُعَرِّفُهَا حَوْلاً فَإِنْ جَاءَ صَاحِبُهَا دَفَعْتَهَا إِلَيْهِ وَإِلاَّ عَرَفْتَ وِكَاءَهَا وَعِفَاصَهَا ثُمَّ أَفِضْهَا فِي مَالِكَ فَإِنْ جَاءَ صَاحِبُهَا فَادْفَعْهَا إِلَيْهِ ‏"‏ ‏.‏
