The hadith continues, Umar took from the camels thirty hiqqah, thirty jadhaah, and forty between thaniyyah and bazil amiha, all of them pregnant. Then he called the brother of the slain man and gave them to him rather than to his father, saying, "I heard the Messenger of Allah ﷺ say, 'The killer receives nothing.'"
حدثنا يعقوب حدثنا أبي عن ابن إسحاق حدثني عبد الله بن أبي نجيح وعمرو بن شعيب كلاهما
الحديث وقال أخذ عمر رضي الله عنه من الإبل ثلاثين حقة وثلاثين جذعة وأربعين ثنية إلى بازل عامها كلها خلفة قال ثم دعا أخا المقتول فأعطاها إياه دون أبيه وقال سمعت رسول الله ﷺ يقول ليس لقاتل شيء
Its chain is daif due to a break in transmission. Mujahid did not meet Umar. See the two hadiths before it.
