Narrated Abu Hurairah:The Messenger of Allah (ﷺ) as saying: No retaliation is payable for a wound caused by a dumb animal, for a mine, and for a well. On the treasure found buried in the land there is a fifth.Abu Dawud said: A dumb animal means an animal which is free and has not tether, and there is no one (as a watchman) with it. It causes harm by day and not by night.
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا سُفْيَانُ، عَنِ الزُّهْرِيِّ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، وَأَبِي، سَلَمَةَ سَمِعَا أَبَا هُرَيْرَةَ، يُحَدِّثُ عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَ " الْعَجْمَاءُ جَرْحُهَا جُبَارٌ وَالْمَعْدِنُ جُبَارٌ وَالْبِئْرُ جُبَارٌ وَفِي الرِّكَازِ الْخُمُسُ " . قَالَ أَبُو دَاوُدَ الْعَجْمَاءُ الْمُنْفَلِتَةُ الَّتِي لاَ يَكُونُ مَعَهَا أَحَدٌ وَتَكُونُ بِالنَّهَارِ وَلاَ تَكُونُ بِاللَّيْلِ .
