Sahih al-Bukhari 4394
Narrated `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."
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا أَبُو عَوَانَةَ، حَدَّثَنَا عَبْدُ الْمَلِكِ، عَنْ عَمْرِو بْنِ حُرَيْثٍ، عَنْ عَدِيِّ بْنِ حَاتِمٍ، قَالَ أَتَيْنَا عُمَرَ فِي وَفْدٍ، فَجَعَلَ يَدْعُو رَجُلاً رَجُلاً وَيُسَمِّيهِمْ فَقُلْتُ أَمَا تَعْرِفُنِي يَا أَمِيرَ الْمُؤْمِنِينَ قَالَ بَلَى، أَسْلَمْتَ إِذْ كَفَرُوا، وَأَقْبَلْتَ إِذْ أَدْبَرُوا، وَوَفَيْتَ إِذْ غَدَرُوا، وَعَرَفْتَ إِذْ أَنْكَرُوا‏.‏ فَقَالَ عَدِيٌّ فَلاَ أُبَالِي إِذًا‏.‏
