Musnad Ahmad 347, 348
It was narrated that ‘Amr bin Shu`aib said:
It was narrated from Mujahid bin Jabr... and he mentioned the same Hadeeth. He said: `Umar (4) took thirty three year-old she-camels, thirty four year-old she-camels and forty she camels between the ages of five and eight years, all of which were pregnant, then he called the brother of the one who had been killed and gave them to him, not to his father. And he said: I heard the Messenger of Allah (ﷺ) say: “The killer gets nothing.`
حَدَّثَنَا هُشَيْمٌ، وَيَزِيدُ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ عَمْرِو بْنِ شُعَيْبٍ، قَالَ قَالَ عُمَرُ رَضِيَ اللَّهُ عَنْهُ لَوْلَا أَنِّي سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ لَيْسَ لِقَاتِلٍ شَيْءٌ لَوَرَّثْتُكَ قَالَ وَدَعَا خَالَ الْمَقْتُولِ فَأَعْطَاهُ الْإِبِلَ

حَدَّثَنَا يَعْقُوبُ حَدَّثَنَا أَبِي عَنِ ابْنِ إِسْحَاقَ حَدَّثَنِي عَبْدُ اللَّهِ بْنُ أَبِي نَجِيحٍ وَعَمْرُو بْنُ شُعَيْبٍ كِلَاهُمَا عَنْ مُجَاهِدِ بْنِ جَبْرٍ فَذَكَرَ الْحَدِيثَ وَقَالَ أَخَذَ عُمَرُ رَضِيَ اللَّهُ عَنْهُ مِنْ الْإِبِلِ ثَلَاثِينَ حِقَّةً وَثَلَاثِينَ جَذَعَةً وَأَرْبَعِينَ ثَنِيَّةً إِلَى بَازِلِ عَامِهَا كُلُّهَا خَلِفَةٌ قَالَ ثُمَّ دَعَا أَخَا الْمَقْتُولِ فَأَعْطَاهَا إِيَّاهُ دُونَ أَبِيهِ وَقَالَ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ لَيْسَ لِقَاتِلٍ شَيْءٌ‏.‏
