Hadith 981:38
Al-Aswad ibn ‘Amir narrated to us, Abu Bakr—meaning Ibn ‘Ayyash—narrated to us, from Layth, from Abu al-Khattab, from Abu Zur‘ah, from Thawban, who said: "The Messenger of Allah (peace and blessings of Allah be upon him) cursed the one who offers the bribe, the one who takes the bribe, and the intermediary," meaning: the one who walks between them.
