Sahih al-Bukhari
Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh))
"Say (O Muhammad ﷺ : 'O mankind. Verily, I am sent to you all as the Messenger of Allah - to Whom belongs the dominion of the heavens and the earth. Lailaha ilIa Huwa (none has the right to be worshipped but He). It is He Who gives life and causes death. So believe in Allah and His Messenger (Muhammad ﷺ,), the Prophet who can neither read nor write (i.e., Muhammad ﷺ) ,who believes in Allah and His Words [(this Qur'an), the Taurat (Torah) and the Injeel (Gpspel) and also Allah's Word: "Be! - and he was, i.e., 'Isa (Jesus) son of Maryam (Mary) ;and follow him so that you may be guided." (V.7:158)
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)." 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 ."
