Sunan an-Nasa'i 2498
It was narrated that Abu Hurairah said:
The Messenger of Allah said: "The injuries caused by the well are without liability, [1] and beasts are without liability, and mines are without liability, and the Khumus is due on Rikaz."
أَخْبَرَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا هُشَيْمٌ، أَنْبَأَنَا مَنْصُورٌ، وَهِشَامٌ، عَنِ ابْنِ سِيرِينَ، عَنْ أَبِي هُرَيْرَةَ، رضى الله عنه قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏
"‏ الْبِئْرُ جُبَارٌ وَالْعَجْمَاءُ جُبَارٌ وَالْمَعْدِنُ جُبَارٌ وَفِي الرِّكَازِ الْخُمْسُ ‏"‏ ‏.‏
