Sunan Ibn Majah 2504
It was narrated from Zaid bin Khalid that the Prophet (ﷺ) was asked about a lost camel. :
He turned red, and he said: “What does it have to do with you? It has its feet and its water supply, it can go and drink water and eat from the trees until its owner finds it.” And he was asked about lost sheep, and he said: “Take it, for it will be for you or for your brother or for the wolf.” And he was asked about lost property and he said: “Remember the features of its leather bag and strap, and announce it for one year, then if someone claims it, describing it to you with those features (give it to him), otherwise incorporate it into your own wealth.”
حَدَّثَنَا إِسْحَاقُ بْنُ إِسْمَاعِيلَ بْنِ الْعَلاَءِ الأَيْلِيُّ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ رَبِيعَةَ بْنِ أَبِي عَبْدِ الرَّحْمَنِ، عَنْ يَزِيدَ، مَوْلَى الْمُنْبَعِثِ عَنْ زَيْدِ بْنِ خَالِدٍ الْجُهَنِيِّ، فَلَقِيتُ رَبِيعَةَ فَسَأَلْتُهُ فَقَالَ حَدَّثَنِي يَزِيدُ، عَنْ زَيْدِ بْنِ خَالِدٍ الْجُهَنِيِّ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ سُئِلَ عَنْ ضَالَّةِ الإِبِلِ فَغَضِبَ وَاحْمَرَّتْ وَجْنَتَاهُ وَقَالَ ‏"‏ مَالَكَ وَلَهَا مَعَهَا الْحِذَاءُ وَالسِّقَاءُ تَرِدُ الْمَاءَ وَتَأْكُلُ الشَّجَرَ حَتَّى يَلْقَاهَا رَبُّهَا ‏"‏ ‏.‏ وَسُئِلَ عَنْ ضَالَّةِ الْغَنَمِ فَقَالَ ‏"‏ خُذْهَا فَإِنَّمَا هِيَ لَكَ أَوْ لأَخِيكَ أَوْ لِلذِّئْبِ ‏"‏ ‏.‏ وَسُئِلَ عَنِ اللُّقَطَةِ فَقَالَ ‏"‏ اعْرِفْ عِفَاصَهَا وَوِكَاءَهَا وَعَرِّفْهَا سَنَةً فَإِنِ اعْتُرِفَتْ وَإِلاَّ فَاخْلِطْهَا بِمَالِكَ ‏"‏ ‏.‏
