"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)
أَنَّ رَسُولَ اللهِ ﷺ قَالَ «أَلَا وَإِنَّ قَتِيلَ الْخَطَأِ شِبْهِ الْعَمْدِ مَا كَانَ بِالسَّوْطِ وَالْعَصَا مِائَةٌ مِنَ الْإِبِلِ مِنْهَا أَرْبَعُونَ فِي بُطُونِهَا أَوْلَادُهَا»
