باب اللَّهْوِ بِالْحِرَابِ وَنَحْوِهَا

Narrated Abu Huraira:

While some Ethiopians were playing in the presence of the Prophet, `Umar came in, picked up a stone and hit them with it. On that the Prophet (ﷺ) said, "O `Umar! Allow them (to play)." Ma`mar (the subnarrator) added that they were playing in the Mosque.

حَدَّثَنَا إِبْرَاهِيمُ بْنُ مُوسَى، أَخْبَرَنَا هِشَامٌ، عَنْ مَعْمَرٍ، عَنِ الزُّهْرِيِّ، عَنِ ابْنِ الْمُسَيَّبِ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ بَيْنَا الْحَبَشَةُ يَلْعَبُونَ عِنْدَ النَّبِيِّ صلى الله عليه وسلم بِحِرَابِهِمْ دَخَلَ عُمَرُ، فَأَهْوَى إِلَى الْحَصَى فَحَصَبَهُمْ بِهَا‏.‏ فَقَالَ ‏ "‏ دَعْهُمْ يَا عُمَرُ ‏"‏‏.‏ وَزَادَ عَلِيٌّ حَدَّثَنَا عَبْدُ الرَّزَّاقِ أَخْبَرَنَا مَعْمَرٌ فِي الْمَسْجِدِ‏.‏
