Jami` at-Tirmidhi Book 49, Hadith 77
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."
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."
from Ibn 'Umar, that the Messenger of Allah (ﷺ) said: "Indeed Allah has put the truth upon the tongue and in the heart of 'Umar." He said: "And Ibn 'Umar said: 'No affair occurred among the people, except that they said something about it, and 'Umar said something about it'" or he said - "Ibn Al-Khattab" - Kharijah (one of the narrators) had a doubt about it - "except that the Qur'an was revealed in line with what 'Umar had said."
