Musannaf Ibn Abi Shayba 13:300

Hafs ibn Ghiyath and 'Abbad narrated to us, from Hajjaj, from Ja'far ibn 'Amr ibn Hurayth, from his father: That a *dihqan* (landowner/official) sent to 'Ali a garment of silk brocade woven with gold—and Hafs said: "inscribed with gold"—and 'Amr ibn Hurayth bought it from him for four thousand dirhams, to be paid at the time of the *'ata'* (stipend/allowance).
