Narrated Abu Hurairah: that the Messenger of Allah ( صلی اللہ علیہ وسلم ) said: "Leadership is among the Quraish, and reasoning and judgment is among the Ansar, and the Adhan is among the Ethiopians, and the trust is among the Al-Azd." meaning Yemen.

Muhammad bin Bashar narrated to us, he said:
Abdulrahman bin Mahdi narrated to us, and Abdulrahman from Muawiyah bin Salih, and Muawiyah from Abu Maryam Ansari, from Abu Hurairah (may Allah be pleased with him), narrated a similar hadith, and he did not attribute it as marfu‘.
Imam Tirmidhi says:
And this hadith is more authentic than the (previous) hadith of Zaid bin Hubab.
