Hadeeth Qudsi 19:

On the authority of AbuHurayrah (may Allah be pleased with him), who said that the Messengerof Allah said: Allah (mighty and sublime be He) said:

Pride is my cloak and greatness Myrobe, and he who competes with Me in respect of either of them I shallcast into Hell-fire.

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