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)."
In the meantime `Umar repented and felt sorry for what he had done, so he came, greeted (those who
were present) and sat with the Prophet (ﷺ) and related the story to him. Allah's Messenger (ﷺ) became angry and
Abu Bakr started saying, "O Allah's Messenger (ﷺ)! By Allah, I was more at fault (than `Umar)." 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 ."
