Narrated Abu Huraira: The people said, "O Allah's Apostle! Who is the most honorable amongst the people (in Allah's Sight)?" He said, "The most righteous amongst them." They said, "We do not ask you, about this. " He said, "Then Joseph, Allah's Prophet, the son of Allah's Prophet, The son of Allah's Prophet the son of Allah's Khalil (i.e. Abraham)." They said, "We do not want to ask about this," He said' "Then you want to ask about the descent of the Arabs. Those who were the best in the pre-lslamic period of ignorance will be the best in Islam provided they comprehend the religious knowledge."

Narrated Abu Huraira: The Prophet said, "The worst people in the Sight of Allah on the Day of Resurrection will be the double faced people who appear to some people with one face and to other people with another face."

Narrated Abu Huraira: Allah's Apostles said, "The worst of all mankind is the double-faced one, who comes to some people with one countenance and to others, with another countenance."
