أَخْبَرَنِي يَحْيَى بْنُ حَبِيبِ بْنِ عَرَبِيٍّ، قَالَ أَنْبَأَنَا حَمَّادٌ، عَنْ خَالِدٍ، - يَعْنِي الْحَذَّاءَ - عَنِ الْقَاسِمِ بْنِ رَبِيعَةَ، عَنْ عُقْبَةَ بْنِ أَوْسٍ، عَنْ عَبْدِ اللَّهِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ أَلاَ وَإِنَّ قَتِيلَ الْخَطَإِ شِبْهِ الْعَمْدِ مَا كَانَ بِالسَّوْطِ وَالْعَصَا مِائَةٌ مِنَ الإِبِلِ أَرْبَعُونَ فِي بُطُونِهَا أَوْلاَدُهَا ‏"‏ ‏.‏

It was narrated from 'Uqbah bin Aws, that

a man from among the Companions of the Prophet delivered a speech on the Day of the Conquest of Makkah and said: 'Indeed the accidental killing, which seems international, with a whip, a stick, or a rock, (the Diyah) is one hundred camels, of which forty should be pregnant she-camels between the ages of six and nine years old, all in the middle of their pregnancies."
