Musnad Ahmad 524
Ibraheem bin Sa’d narrated:
My father narrated; that his father said: Uthman said: If you find in the Book of Allah, may He be glorified and exalted, that you should put my feet in fetters, then do that.
حَدَّثَنَا عَبْد اللَّهِ، حَدَّثَنَا سُوَيْدٌ، حَدَّثَنَا إِبْرَاهِيمُ بْنُ سَعْدٍ، حَدَّثَنِي أَبِي، عَنْ أَبِيهِ، قَالَ قَالَ عُثْمَانُ إِنْ وَجَدْتُمْ فِي كِتَابِ اللَّهِ عَزَّ وَجَلَّ أَنْ تَضَعُوا رِجْلِي فِي الْقَيْدِ فَضَعُوهَا‏.‏
