It is narrated from Ibn Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Beware! Indeed, for a person killed by intentional mistake (who dies from a whip or a stick), there are one hundred large camels (as blood money). Among them, forty are pregnant camels with young in their wombs."
