[Machine] "Indeed, a grandfather does not hold the same position as a father in your eyes, and you do not deny." He (the interrogator) said, "I said, even if you were (the father), you would not deny." Marwan said, "I bear witness regarding Uthman bin Affan that he testified regarding Abu Bakr that he made the grandfather (as) a father when there is no father."  

الدارمي:٢٩٥١أَخْبَرَنَا الْأَسْوَدُ بْنُ عَامِرٍ حَدَّثَنَا شُعْبَةُ عَنْ عَمْرِو بْنِ مُرَّةَ عَنْ أَبِي بُرْدَةَ قَالَ لَقِيتُ مَرْوَانَ بْنَ الْحَكَمِ بِالْمَدِينَةِ فَقَالَ يَا ابْنَ أَبِي مُوسَى أَلَمْ أُخْبَرْ

أَنَّ الْجَدَّ لَا يُنَزَّلُ فِيكُمْ مَنْزِلَةَ الْأَبِ وَأَنْتَ لَا تُنْكِرُ؟ قَالَ قُلْتُ وَلَوْ كُنْتَ أَنْتَ لَمْ تُنْكِرْ قَالَ مَرْوَانُ فَأَنَا أَشْهَدُ عَلَى عُثْمَانَ بْنِ عَفَّانَ أَنَّهُ شَهِدَ عَلَى أَبِي بَكْرٍ «أَنَّهُ جَعَلَ الْجَدَّ أَبًا إِذَا لَمْ يَكُنْ دُونَهُ أَبٌ»
