Sahih Bukhari | Volume 5 | Hadith Number 677

Narrated by 'Adi bin Hatim
We came to 'Umar in a delegation (during his rule). He started calling the men one by one, calling each by his name. (As he did not call me early) I said to him. "Don't you know me, O chief of the Believers?" He said, "Yes, you embraced Islam when they (i.e.

your people) disbelieved; you have come (to the Truth) when they ran away; you fulfilled your promises when they broke theirs; and you recognized it (i.e. the Truth of Islam) when they denied it." On that, 'Adi said, "I therefore don't care."
