"Indeed the accidental killing, which seems intentional, with a whip or a stick, (the Diyah) is one hundred camels, of which forty should be (she-camels) with their young in their wombs." (Using translation from Nasāʾī 4793)   

قَالَ رَسُولُ اللَّهِ ﷺ «دِيَةُ قَتِيلِ الْخَطَإِ شِبْهِ الْعَمْدِ وَمَا كَانَ بِالسَّوْطِ وَالْعَصَا مِنْهَا أَرْبَعُونَ فِي بُطُونِهَا أَوْلَادُهَا»
