It was narrated that Ibn 'Umar said: "The Messenger of Allah (ﷺ) stood up on the Day of the Conquest of Makkah, on the steps of Ka'bah. He praised and glorified Allah, then he said: 'Praise be to Allah who has fulfilled His slave and defeated the confederates alone. The one who is killed purposefully by mistake, with a whip or a stick, resembling on purpose, for that (the Diyah) is one hundred camels-a severe penalty-of which forty should be pregnant she-camels with their young in their wombs."'
