‘Umar wrote to AbuʼUbaidah bin al-Jarrah [saying]: Teach your children swimming and teach your fighters archery. After that they used to practise archery frequently, then a stray arrow came and killed a boy, and no one knew where it came from; he was under the care of his maternal uncle. Abu ʿUbaidah wrote to ʿUmar about that [asking]: To whom should I pay his diyah? ‘Umar wrote back telling him that the Messenger of Allah ﷺ used to say: “Allah and His Messenger are the mawla (guardian) of the one who has no mawla, and the maternal uncle is the heir of the one who has no heir.”  

أَنْ عَلِّمُوا غِلْمَانَكُمُ الْعَوْمَ وَمُقَاتِلَتَكُمُ الرَّمْيَ فَكَانُوا يَخْتَلِفُونَ إِلَى الْأَغْرَاضِ فَجَاءَ سَهْم غَرْبٌ إِلَى غُلامٍ فَقَتَلَهُ فَلَمْ يُوجَدْ لَهُ أَصْلٌ وَكَانَ فِي حِجْرِ خَالٍ لَهُ فَكَتَبَ فِيهِ أَبُو عُبَيْدَةَ إِلَى عُمَرَ [[إِلَى مَنْ أَدْفَعُ عَقْلَهُ؟]] (*) فَكَتَبَ إِلَيْهِ عُمَرُ إِنَّ رَسُولَ اللهِ ﷺ كَانَ يَقُولُ اللهُ وَرَسُولُهُ مَوْلَى مَنْ لَا مَوْلَى لَهُ وَالْخَالُ وَارِثُ مَنْ لَا وَارِثَ لَهُ  

[Machine] Umar wrote to Abu Ubaydah: Teach your boys swimming and archery. Abu Ubaydah said: They had different opinions about these matters. Then, an arrow came from the west and hit a boy, killing him. The boy's uncle was the only one who knew about the boy's family. Abu Ubaydah wrote to Umar and informed him about the boy's incident and asked to whom his compensation should be given. Umar wrote back to him and said: The Messenger of Allah ﷺ said, "Allah and His Messenger are protectors of those who have no protector, and the uncle is the inheritor of those who have no inheritor."  

كَتَبَ عُمَرُ ؓ إِلَى أَبِي عُبَيْدَةَ أَنْ عَلِّمُوا صِبْيَانَكُمُ الْعَوْمَ وَمُقَاتِلَتَكُمُ الرَّمْيَ قَالَ فَكَانُوا يَخْتَلِفُونَ بَيْنَ الْأَغْرَاضِ قَالَ فَجَاءَ سَهْمٌ غَرْبٌ فَأَصَابَ غُلَامًا فَقَتَلَهُ وَلَمْ يُعْلَمْ لِلْغُلَامِ أَهْلٌ إِلَّا خَالُهُ فَكَتَبَ أَبُو عُبَيْدَةَ إِلَى عُمَرَ فَذَكَرَ لَهُ شَأْنَ الْغُلَامِ إِلَى مَنْ يَدْفَعُ عَقْلَهُ فَكَتَبَ إِلَيْهِ أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «اللَّهُ وَرَسُولُهُ مَوْلَى مَنْ لَا مَوْلَى لَهُ وَالْخَالُ وَارِثُ مَنْ لَا وَارِثَ لَهُ»
