Musannaf Ibn Abi Shayba 18:1307

Abu Bakr narrated to us, he said: Ma'n ibn 'Isa narrated to us, from Ibn Abi Dhi'b, from al-Zuhri, regarding a woman who was struck and miscarried three fetuses: He said: I am of the opinion that for each one of them there is a *ghurra* (compensation), just as for each one of them there is the *diya* (blood money).
