Musannaf Ibn Abi Shayba 13:2006

Abu Bakr narrated to us, he said: Ibn Abi Za'idah narrated to us, from Layth, from Abu al-Khattab, from Abu Zur'ah, from Abu Idris, from Thawban, who said: The Prophet, peace and blessings of Allah be upon him, cursed the one who offers the bribe, the one who takes the bribe, and the *ra'ish*—meaning the one who walks between them.
