Musannaf Ibn Abi Shayba 13:2243

Abu Bakr narrated to us, he said: Ibn ‘Uyaynah narrated to us, from Mujammi’ al-Ansari, he said: I heard Khalid ibn Sa’d, the freed slave of Abu Mas’ud, say: I heard Abu Hurayrah say: Lying is the salt of a sale; it makes the merchandise sell, but it wipes out the profit.
