صحيح البخاري#3494SahihNarrated Abu Huraira:Allah's Messenger (ﷺ) said, "You see that the people are of different natures. Those who were the best in the pre-Islamic period, are also the best in Islam if they comprehend religious knowledge. You see that the best amongst the people in this respect (i.e. ambition of ruling) are those who hate it most. And you see that the worst among people is the double faced (person) who appears to these with one face and to the others with another face (i.e a hypocrite)
