Mishkat al-Masabih 16 Retaliation كتاب القصاص 55

وَعَن مُجاهدٍ قَالَ: قَضَى عُمَرُ رَضِيَ اللَّهُ عَنْهُ فِي شِبْهِ الْعَمْدِ ثَلَاثِينَ حِقَّةً وَثَلَاثِينَ جَذَعَةً وَأَرْبَعِينَ خَلِفَةً مَا بَيْنَ ثَنِيَّةٍ إِلَى بَازِلِ عَامِهَا. رَوَاهُ أَبُو دَاوُد

Mujahid said ‘Umar gave judgment that the blood wit for what resembled intentional murder should be thirty she-camels in their fourth year, thirty she-camels in their fifth year, and forty pregnant she-camels in their sixth year up to the ninth. Abu Dawud transmitted it.
