As-salaamu'alaykum,
Anas ibn Malik said,
One day, I heard Umar ibn al-Khattaab voice and so I went out and followed him. He soon entered a garden and even though the two of us were separated by a wall with him on the inside (and me on the outside), I could hear him say,
Umar ibn al-Khattaab is the Leader of the Believers. Indeed! By Allah, O small son of al-Khattaab, you will fear Allah or He will indeed punish you.
(Imam Malik al-Muwatta, 2/992 and the chain of this narration is authentic)
