Mukhtasar Bukhari

Sayyiduna Abu Darda (may Allah be pleased with him) says: I was sitting with the Prophet (peace and blessings of Allah be upon him) when Sayyiduna Abu Bakr (may Allah be pleased with him) came, lifting the corner of his garment until his knee became exposed. The Prophet (peace and blessings of Allah be upon him) said: "Your companion (Abu Bakr) has come after having a quarrel with someone." Sayyiduna Abu Bakr (may Allah be pleased with him) greeted (with salam) and said: O Messenger of Allah! There was some argument between me and Ibn Khattab (Sayyiduna Umar, may Allah be pleased with him), and I hastily spoke harshly to him. Then I regretted it and asked him for forgiveness, but he refused. So I have come to you (so that you may advise him). The Prophet (peace and blessings of Allah be upon him) said: "Abu Bakr! May Allah forgive you." He said this three times. Then Sayyiduna Umar (may Allah be pleased with him) felt remorse and came to the house of Sayyiduna Abu Bakr (may Allah be pleased with him) and asked: Is Abu Bakr here? The people (of the house) said: No. So he went to the Prophet (peace and blessings of Allah be upon him) and greeted (with salam), and the color of the Prophet’s face began to change, until Sayyiduna Abu Bakr (may Allah be pleased with him) became afraid (that the Prophet, peace and blessings of Allah be upon him, might become upset with Sayyiduna Umar, may Allah be pleased with him), so he knelt down and said: O Messenger of Allah! By Allah, it was my fault. He said this twice. Then the Prophet (peace and blessings of Allah be upon him) said: "(O people!) Allah sent me to you as a Prophet, but you denied me, and Abu Bakr affirmed me, and he supported me with his wealth and his life. Will you not, for my sake, leave my companion alone?" He said this twice. After that, no one ever troubled Sayyiduna Abu Bakr (may Allah be pleased with him) again.
