Musannaf Ibn Abi Shayba 18:1305

Abu Bakr narrated to us, he said: Hafs narrated to us, from Abu Talq, from his sister Hind bint Talq, who said: I was among a group of women, and a young boy was covered. She said: A woman passed by and stepped on him. The boy’s mother said: "She killed him, by Allah!" She said: Ten women testified before Ali, and I was the tenth of them. So he judged against her [the woman who stepped on the boy] to pay the blood money (diyah), and he assisted her with two thousand.
