Musannaf Ibn Abi Shayba 28:376

Waki’ narrated to us, he said: Sharik narrated to us, from Ibrahim ibn al-Muhajir, from Qays ibn Abi Hazim al-Ahmasi, who said: A man came to the Messenger of Allah (may Allah bless him and grant him peace) with a bundle of hair from the spoils of war. He said: "O Messenger of Allah, grant it to me, for we are a household that works with hair." He said: "My share of it is for you."
