Musannaf Ibn Abi Shayba 18:12

Jafar Abu Bakr narrated to us, he said: Yahya ibn Adam narrated to us, he said: Sufyan ibn Uyaynah narrated to us, from Ali ibn Zayd ibn Jud'an, from al-Qasim ibn Rabi'ah, from Ibn Umar, he said: The Messenger of Allah (may Allah bless him and grant him peace) delivered a sermon on the day of the conquest of Makkah. He stood on the steps of the Kaaba and said: "Praise be to Allah who fulfilled His promise, aided His servant, and defeated the confederates alone. Beware, for the one killed by intentional-like error with a whip or a stick, the blood money for it is intensified: one hundred camels, forty of which are pregnant, carrying their offspring in their wombs."
