The Prophet ﷺ said: Beware, the fanged beast of prey is not lawful, nor the domestic asses, nor the find from the property of a man with whom treaty has been concluded, except that he did not need it. If anyone is a guest of people who provide no hospitality for him, he is entitled to take from them the equivalent of the hospitality due to him.
عَنْ رَسُولِ اللَّهِ ﷺ قَالَ أَلاَ لاَ يَحِلُّ ذُو نَابٍ مِنَ السِّبَاعِ وَلاَ الْحِمَارُ الأَهْلِيُّ وَلاَ اللُّقَطَةُ مِنْ مَالِ مُعَاهِدٍ إِلاَّ أَنْ يَسْتَغْنِيَ عَنْهَا وَأَيُّمَا رَجُلٍ ضَافَ قَوْمًا فَلَمْ يَقْرُوهُ فَإِنَّ لَهُ أَنْ يُعْقِبَهُمْ بِمِثْلِ قِرَاهُ
