It was narrated from 'Uqbah bin 'Aws, that the Mssenger of Allah said:

"Indeed the accidental killing, the killing with a whip or stick, for it (the Diyah) is one hundred camels - a severe penalty - of which forty should be (she-camels) with their young in their wombs."

أَخْبَرَنَا مُحَمَّدُ بْنُ بَشَّارٍ، عَنِ ابْنِ أَبِي عَدِيٍّ، عَنْ خَالِدٍ، عَنِ الْقَاسِمِ، عَنْ عُقْبَةَ بْنِ أَوْسٍ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ " أَلاَ إِنَّ قَتِيلَ الْخَطَإِ قَتِيلَ السَّوْطِ وَالْعَصَا فِيهِ مِائَةٌ مِنَ الإِبِلِ مُغَلَّظَةٌ أَرْبَعُونَ مِنْهَا فِي بُطُونِهَا أَوْلاَدُهَا " .
