Musannaf Ibn Abi Shayba 13:1169

Abu Bakr narrated to us, he said: Waki’ narrated to us, he said: Shu’bah narrated to us, from al-Hakam, he said: I was walking between Ibrahim and al-Sha’bi, and he was asked about the plundering of sugar at a wedding. Ibrahim disliked it, while al-Sha’bi saw no harm in it.
