ذِكْرُ السَّبَبِ الَّذِي هُوَ مُضْمَرٌ فِي نَفْسِ الْخِطَابِ الَّذِي تَقَدَّمَ ذِكْرُنَا لَهُ
Make announcement of that for one year, but if it is not recognised (by the owner), then recognise its big and strap, then eat it; and if its owner comes, then give that to him. This hadith has been narrated on the authority of Al-Dahhak b. Uthman with the same chain of transmitters but with a slight variation of words. (Using translation from Muslim 1722g)
سُئِلَ رَسُولُ اللَّهِ ﷺ عَنِ اللُّقَطَةِ فَقَالَ «عَرِّفْهَا سَنَةً فَإِنْ لَمْ تَعْرِفْ فَاعْرِفْ عِفَاصَهَا وَوِكَاءَهَا ثُمَّ كُلْهَا فَإِنْ جَاءَ صَاحِبُهَا فَأَدِّهَا إِلَيْهِ»
