Abu Bakr said to the delegate of Buzakha. "Follow the tails of the camels till Allah shows the Caliph (successor) of His Prophet and Al-Muhajirin (emigrants) something because of which you may excuse yourselves."
Sahih al-Bukhari Book 93, Hadith 81
← Previous Hadith A woman came to the Prophet (ﷺ) and spoke to him about something and he told her to return to him. She said, "O Allah's Messenger (ﷺ)! If I come and do not find you?" (As if she meant, "...if you die?") The Prophet said, "If you should not find me, then go to Abu Bakr."

Sahih al-Bukhari Book 93, Hadith 80 Next Hadith → I heard the Prophet (ﷺ) saying, "There will be twelve Muslim rulers (who will rule all the Islamic world)." He then said a sentence which I did not hear. My father said, "All of them (those rulers) will be from Quraish."
