(30) باب لاَ تَحْقِرَنَّ جَارَةٌ لِجَارَتِهَا
Sahih al-Bukhari 6017 

Narrated Abu Huraira:

The Prophet (ﷺ) used to say, "O Muslim ladies! A neighbouress should not look down upon the present of her neighbouress even it were the hooves of a sheep."

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، حَدَّثَنَا اللَّيْثُ، حَدَّثَنَا سَعِيدٌ ـ هُوَ الْمَقْبُرِيُّ ـ عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ كَانَ النَّبِيُّ صلى الله عليه وسلم يَقُولُ ‏ "‏ يَا نِسَاءَ الْمُسْلِمَاتِ لاَ تَحْقِرَنَّ جَارَةٌ لِجَارَتِهَا وَلَوْ فِرْسِنَ شَاةٍ ‏"‏‏.‏
