وَعَنْ عَبْدِ اَللَّهِ بْنِ مُغَفَّلٍ - رضى الله عنه - أَنَّ اَلنَّبِيَّ - صلى الله عليه وسلم -قَالَ: { مَنْ حَفَرَ بِئْرًا فَلَهُ أَرْبَعُونَ ذِرَاعًا عَطَنًا لِمَاشِيَتِهِ } رَوَاهُ اِبْنُ مَاجَهْ بِإِسْنَادٍ ضَعِيفٍ [1] .
Narrated 'Abdullah bin Mughaffal (RA): The Prophet (ﷺ), "Whoever digs a well, shall have forty cubits (of land) as resting place for his animals near the water." [Reported by Ibn Majah through a weak chain of narrators].
