[Machine] Abu Bakr, Ibn Abbas, and Ibn Zubair are all biological fathers. Ibn Abbas recited, "O children of Adam" and "I have followed the religion of my fathers, Abraham, Isaac, and Jacob." It is not mentioned that anyone disagreed with Abu Bakr during his time, and the companions of the Prophet ﷺ are present. Ibn Abbas said, "My grandson will inherit from me, not my brothers, and I will not inherit from my grandson." Various statements are attributed to Umar, Ali, Ibn Masud, and Zaid.

وَقَالَ أَبُو بَكْرٍ وَابْنُ عَبَّاسٍ وَابْنُ الزُّبَيْرِ الْجَدُّ أَبٌ. وَقَرَأَ ابْنُ عَبَّاسٍ: {يَا بَنِي آدَمَ}، {وَاتَّبَعْتُ مِلَّةَ آبَائِي إِبْرَاهِيمَ وَإِسْحَاقَ وَيَعْقُوبَ}. وَلَمْ يُذْكَرْ أَنَّ أَحَدًا خَالَفَ أَبَا بَكْرٍ فِي زَمَانِهِ وَأَصْحَابُ النَّبِيِّ ﷺ مُتَوَافِرُونَ. وَقَالَ ابْنُ عَبَّاسٍ: يَرِثُنِي ابْنُ ابْنِي دُونَ إِخْوَتِي، وَلاَ أَرِثُ أَنَا ابْنَ ابْنِي. وَيُذْكَرُ عَنْ عُمَرَ وَعَلِيٍّ وَابْنِ مَسْعُودٍ وَزَيْدٍ أَقَاوِيلُ مُخْتَلِفَةٌ.
