Jami` at-Tirmidhi Book 49, Hadith 76
that the Messenger of Allah (ﷺ) said: "There is no Prophet except that he has two ministers among the inhabitants of the heavens, and two ministers among the inhabitants of the earth. As for my two ministers from the inhabitants of the heavens, then they are Jibril and Mika'il, and as for my two ministers from the inhabitants of the earth, then they are Abu Bakr and 'Umar."
that Abu Bakr entered upon the Messenger of Allah (ﷺ), so he said: "You are Allah's 'Atiq from the Fire." From that day on he was called 'Atiq.
that the Messenger of Allah (ﷺ) said: "O Allah! Honor Islam through the most dear of these two men to you: Through Abu Jahl or through 'Umar bin Al-Khattab." He said: "And the most dear of them to Him was 'Umar."
