Sunan an-Nasa'i 4800
It was narrated from Al- Qasim bin Rabi'ah that the Messenger jof Allah said:
"The accident that resembles on purpose, meaning (killing) with a stick or a whip, (for which the Diyah is) one hundred camels, of which forty should be (pregnant she-camels), with their young in their wombs."
أَخْبَرَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، قَالَ حَدَّثَنَا سَهْلُ بْنُ يُوسُفَ، قَالَ حَدَّثَنَا حُمَيْدٌ، عَنِ الْقَاسِمِ بْنِ رَبِيعَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏
"‏ الْخَطَأُ شِبْهُ الْعَمْدِ - يَعْنِي بِالْعَصَا وَالسَّوْطِ - مِائَةٌ مِنَ الإِبِلِ مِنْهَا أَرْبَعُونَ فِي بُطُونِهَا أَوْلاَدُهَا ‏"‏ ‏.‏
