Narrated Abu Ad-Darda: There was a dispute between Abu Bakr and `Umar, and Abu Bakr made `Umar angry. So `Umar left angrily. Abu Bakr followed him, requesting him to ask forgiveness (of Allah) for him, but `Umar refused to do so and closed his door in Abu Bakr's face. So Abu Bakr went to Allah's Messenger (ﷺ) while we were with him. Allah's Messenger (ﷺ) said, "This friend of yours must have quarrelled (with somebody)."

Allah's Apostle said, "Are you (people) leaving for me my companion? (Abu Bakr), Are you (people) leaving for me my companion? When I said, 'O people I am sent to you all as the Messenger of Allah,' you said, 'You tell a lie.' while Abu Bakr said, 'You have spoken the truth ."
