Sahih al-Bukhari, Hadith 4666 ⓘ

Narrated Ibn Abi Mulaika: We entered upon Ibn `Abbas and he said "Are you not astonished at Ibn Az-Zubair's assuming the caliphate?" I said (to myself), "I will support him and speak of his good traits as I did not do even for Abu Bakr and `Umar though they were more entitled to receive al I good than he was." I said "He (i.e Ibn Az-Zubair) is the son of the aunt of the Prophet and the son of AzZubair, and the grandson of Abu Bakr and the son of Khadija's brother, and the son of `Aisha's sister." Nevertheless, he considers himself to be superior to me and does not want me to be one of his friends. So I said, "I never expected that he would refuse my offer to support him, and I don't think he intends to do me any good, therefore, if my cousins should inevitably be my rulers, it will be better for me to be ruled by them than by some others."

حَدَّثَنَا مُحَمَّدُ بْنُ عُبَيْدِ بْنِ مَيْمُونٍ، حَدَّثَنَا عِيسَى بْنُ يُونُسَ، عَنْ عُمَرَ بْنِ سَعِيدٍ، قَالَ أَخْبَرَنِي ابْنُ أَبِي مُلَيْكَةَ، دَخَلْنَا عَلَى ابْنِ عَبَّاسٍ فَقَالَ أَلاَ تَعْجَبُونَ لاِبْنِ الزُّبَيْرِ قَامَ فِي أَمْرِهِ هَذَا فَقُلْتُ لأُحَاسِبَنَّ نَفْسِي لَهُ مَا حَاسَبْتُهَا لأَبِي بَكْرٍ وَلاَ لِعُمَرَ، وَلَهُمَا كَانَا أَوْلَى بِكُلِّ خَيْرٍ مِنْهُ، وَقُلْتُ ابْنُ عَمَّةِ النَّبِيِّ صلى الله عليه وسلم، وَابْنُ الزُّبَيْرِ، وَابْنُ أَبِي بَكْرٍ، وَابْنُ أَخِي خَدِيجَةَ، وَابْنُ أُخْتِ عَائِشَةَ فَإِذَا هُوَ يَتَعَلَّى عَنِّي وَلاَ يُرِيدُ ذَلِكَ فَقُلْتُ مَا كُنْتُ أَظُنُّ أَنِّي أَعْرِضُ هَذَا مِنْ نَفْسِي، فَيَدَعُهُ، وَمَا أُرَاهُ يُرِيدُ خَيْرًا، وَإِنْ كَانَ لاَ بُدَّ لأَنْ يَرُبَّنِي بَنُو عَمِّي أَحَبُّ إِلَىَّ مِنْ أَنْ يَرُبَّنِي غَيْرُهُمْ‏.‏
