أَبَانٌ عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي عَبْدِ اللَّهِ عَنْ أَبِي الْعَبَّاسِ الْمَكِّيِّ قَالَ سَمِعْتُ أَبَا جَعْفَرٍ (عليه السلام) يَقُولُ إِنَّ عُمَرَ لَقِيَ أَمِيرَ الْمُؤْمِنِينَ (عليه السلام) فَقَالَ أَنْتَ الَّذِي تَقْرَأُ هَذِهِ الْآيَةَ بِأَيِّكُمُ الْمَفْتُونُ تَعَرُّضاً بِي وَ بِصَاحِبِي قَالَ أَ فَلَا أُخْبِرُكَ بِآيَةٍ نَزَلَتْ فِي بَنِي أُمَيَّةَ فَهَلْ عَسَيْتُمْ إِنْ تَوَلَّيْتُمْ أَنْ تُفْسِدُوا فِي الْأَرْضِ وَ تُقَطِّعُوا أَرْحامَكُمْ فَقَالَ كَذَبْتَ بَنُو أُمَيَّةَ أَوْصَلُ لِلرَّحِمِ مِنْكَ وَ لَكِنَّكَ أَبَيْتَ إِلَّا عَدَاوَةً لِبَنِي تَيْمٍ وَ عَدِيٍّ وَ بَنِي أُمَيَّةَ.
325. Abaan, from Abdul Rahmaan Bin Abu Abdullah, from Abu Al-Abbas Al-Makky who said: I heard Abu Ja’far  saying that: ‘Umar met Amir-ul-Momineen  and said, ‘You  are the one who recites this Verse: “[68:6] Which of you is afflicted with madness”, applying it to me and my companion (abu Bakr)’. He  said: ‘Shall I  not inform you of the Verse which Descended regarding the Clan of Umayya: “[47:22] But if you held command, you were sure to make mischief in the land and cut off the ties of kinship!”. So he said, ‘You  are lying. The Clan of Umayya establish more ties of kinship than you  do, but you  are most insistent upon enmity to the Clan of Taym (Abu Bakr’s tribe) and Udayy (Umar’s tribe), and the Clan of Umayya’.
