Musnad Ahmad 30:2236

'Affan narrated to us, Hammad ibn Salamah narrated to us, from 'Ata' ibn al-Sa'ib, from al-Agharr, from Abu Hurayrah, from the Prophet (peace and blessings of Allah be upon him), in what he narrates from his Lord (Mighty and Majestic is He), who said: "Pride is My cloak, and greatness is My lower garment. Whoever disputes with Me regarding either of them, I will cast him into the Fire."
