Sahih al-Bukhari 4664

Narrated Ibn Abi Mulaika:

When there happened the disagreement between Ibn Az-Zubair and Ibn `Abbas, I said (to the latter), "(Why don't you take the oath of allegiance to him as) his father is Az-Zubair, and his mother is Asma,' and his aunt is `Aisha, and his maternal grandfather is Abu Bakr, and his grandmother is Safiya?"

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ، حَدَّثَنَا ابْنُ عُيَيْنَةَ، عَنِ ابْنِ جُرَيْجٍ، عَنِ ابْنِ أَبِي مُلَيْكَةَ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ أَنَّهُ قَالَ حِينَ وَقَعَ بَيْنَهُ وَبَيْنَ ابْنِ الزُّبَيْرِ قُلْتُ أَبُوهُ الزُّبَيْرُ، وَأُمُّهُ أَسْمَاءُ، وَخَالَتُهُ عَائِشَةُ، وَجَدُّهُ أَبُو بَكْرٍ، وَجَدَّتُهُ صَفِيَّةُ‏.‏ فَقُلْتُ لِسُفْيَانَ إِسْنَادُهُ‏.‏ فَقَالَ حَدَّثَنَا، فَشَغَلَهُ إِنْسَانٌ وَلَمْ يَقُلِ ابْنُ جُرَيْجٍ‏.‏
