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

بَيْنَا الْحَبَشَةُ يَلْعَبُونَ عِنْدَ النَّبِيِّ ﷺ بِحِرَابِهِمْ دَخَلَ عُمَرُ فَأَهْوَى إِلَى الْحَصَى فَحَصَبَهُمْ بِهَا فَقَالَ دَعْهُمْ يَا عُمَرُ وَزَادَ عَلِيٌّ حَدَّثَنَا عَبْدُ الرَّزَّاقِ أَخْبَرَنَا مَعْمَرٌ فِي الْمَسْجِدِ  

While the Abyssinians were busy playing with their arms in the presence of the Messenger of Allah ﷺ 'Umar b. Khattab came there. He bent down to take up pebbles to throw at them (in order to make them go off). The Messenger of Allah ﷺ said to him: 'Umar, leave them alone.  

بَيْنَمَا الْحَبَشَةُ يَلْعَبُونَ عِنْدَ رَسُولِ اللَّهِ ﷺ بِحِرَابِهِمْ إِذْ دَخَلَ عُمَرُ بْنُ الْخَطَّابِ فَأَهْوَى إِلَى الْحَصْبَاءِ يَحْصِبُهُمْ بِهَا فَقَالَ لَهُ رَسُولُ اللَّهِ ﷺ دَعْهُمْ يَا عُمَرُ  

[Machine] While the Abyssinians were playing with their spears, Umar entered and leaned on the stones, then the Messenger of Allah ﷺ said, "Leave them, O Umar."  

بَيْنَمَا الْحَبَشَةُ يَلْعَبُونَ بِحِرَابِهِمْ إِذْ دَخَلَ عُمَرُ فَأَهْوَى إِلَى الْحَصَا فَحَصَبَهُمْ فَقَالَ رَسُولُ اللَّهِ ﷺ «دَعْهُمْ يَا عُمَرُ»  

[Machine] While the Habasha (Ethiopians) were playing near the Messenger of Allah ﷺ with their spears, Umar entered and leaned towards the rocks. They threw stones at him and the Messenger of Allah ﷺ said to him, "Leave them, Umar."  

بَيْنَا الْحَبَشَةُ يَلْعَبُونَ عِنْدَ رَسُولِ اللهِ ﷺ بِحِرَابِهِمْ دَخَلَ عُمَرُ فَأَهْوَى إِلَى الْحَصْبَاءِ فَحَصَبَهُمْ بِهَا فَقَالَ لَهُ رَسُولُ اللهِ ﷺ دَعْهُمْ يَا عُمَرُ
