Sunan Ibn Majah, Hadith 2487 ⓘ
It was narrated from Abu Sa'eed Al-Khudri that the Messenger of Allah said: “The land around a well (that is considered to be part of it) is the length of the well rope (in all directions).”
حَدَّثَنَا سَهْلُ بْنُ أَبِي الصُّغْدِيِّ، حَدَّثَنَا مَنْصُورُ بْنُ صُقَيْرٍ، حَدَّثَنَا ثَابِتُ بْنُ مُحَمَّدٍ، عَنْ نَافِعٍ أَبِي غَالِبٍ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " حَرِيمُ الْبِئْرِ مَدُّ رِشَائِهَا " .
