Musannaf Ibn Abi Shaybah 25813 — Aqiqah: those who held it

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that he said: the Messenger of Allah (peace and blessings be upon him) slaughtered one goat as aqiqah on behalf of Sayyiduna Hasan (may Allah be pleased with him), and he said: "O Fatimah, shave his head and give the weight of his hair in silver in charity." So they weighed the hair, and its weight was a dirham or part of a dirham.
