On the authority of Abu Hurayrah (may Allah be pleased with him), who said that the Messenger of Allah (PBUH) said: Allah (mighty and sublime be He) said:

Pride is my cloak and greatness My robe, and he who competes with Me in respect of either of them I shall cast into Hell-fire.

It was related by Abu Dawud (also by Ibn Majah and Ahmad) with sound chains of authority. This Hadith also appears in Muslim in another version.
