Sahih Muslim Book 32, Hadith Number 6247.

Chapter : It is forbidden to commit oppression.

Abu Dharr reported Allah’s Messenger (may peace be upon him) as saying that he reported it from his Lord, the Exalted and Glorious: Verily I have made oppression unlawful for Me and for My servants too, so do not commit oppression. The rest of the hadith is the same.
