Musannaf Ibn Abi Shayba 13:2316

Abu Bakr narrated to us, he said: Abu Usama and Ibn Numayr narrated to us, from Ubayd Allah ibn Umar, from Khubayb ibn Abd al-Rahman, from Hafs ibn Asim, from Abu Hurayrah, that the Messenger of Allah (may Allah bless him and grant him peace) forbade *al-munabadhah* (the throwing of goods) and *al-mulamasah* (the touching of goods).
