Narrated al-Miqdam bin Ma'dikarib (RA):

Allah's Messenger (ﷺ) said: "A beast of prey with a fang, a domestic donkey, and a lost item from the property of a Mu'ahid (a disbeliever who has been given a covenant) - unless it is something worthless - are not lawful." [Reported by Abu Dawud].

وَعَنْ اَلْمِقْدَامِ بْنِ مَعْدِي كَرِبَ ‏- رضى الله عنه ‏- قَالَ : قَالَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-{ أَلَا لَا يَحِلُّ ذُو نَابٍ مِنَ السِّبَاعِ , وَلَا اَلْحِمَارُ اَلْأَهْلِيُّ , وَلَا اَللُّقَطَةُ مِنْ 57 مَالِ مُعَاهَدٍ , إِلَّا أَنْ يَسْتَغْنِيَ عَنْهَا } رَوَاهُ أَبُو دَاوُدَ [1]‏ .‏
