Hadith Qudsi Number 5 : The Authority Of Abu Hurayrah

The Messenger of Allah (peace be upon him) said : “Allah (glorified and exalted be He) said : I am so self-sufficient that I am in no need of having an associate. Thus he who does an action for someone else’s sake as well as Mine will have that action renounced by Me to him whom he associated with Me.”

It was related by Muslim (also by Ibn Majah).
