It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "When Allah Almighty created the creation, He sent Jibril (peace be upon him), and he divided people into two parts: he made the Arabs one part and the non-Arabs the other part, and Allah's chosen group was among the Arabs. Then he divided the Arabs into two parts: he made Yemen one part, and Mudar one part, and Quraysh one part, and Allah's chosen group was among Quraysh. Then He brought me forth from the best of those from whom I come."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) only with this chain; Bishr bin Mu'adh is alone in narrating it."
It is like this in the Dar al-Haramayn edition, whereas the correct form is 'Muhammad bin Abd al-Rahman bin al-Raddad'.
