Musannaf Ibn Abi Shayba 28:675

Waki' narrated to us, he said: Sufyan and Isra'il narrated to us, from Abu Ishaq, he said: We witnessed a military expedition with Sa'id ibn 'Uthman, and Hani' ibn Hani' was with me, and I had two horses with me, and Hani' had a horse with him. So he allotted for me and for the two horses five shares, and he allotted for Hani' and for his horse five shares.
