حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، حَدَّثَنَا سُفْيَانُ، حَدَّثَنَا جَامِعُ بْنُ أَبِي رَاشِدٍ، حَدَّثَنَا أَبُو يَعْلَى، عَنْ مُحَمَّدِ ابْنِ الْحَنَفِيَّةِ، قَالَ قُلْتُ لأَبِي أَىُّ النَّاسِ خَيْرٌ بَعْدَ رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَ أَبُو بَكْرٍ ‏.‏ قَالَ قُلْتُ ثُمَّ مَنْ قَالَ ثُمَّ عُمَرُ ‏.‏ قَالَ ثُمَّ خَشِيتُ أَنْ أَقُولَ ثُمَّ مَنْ فَيَقُولَ عُثْمَانُ فَقُلْتُ ثُمَّ أَنْتَ يَا أَبَةِ قَالَ مَا أَنَا إِلاَّ رَجُلٌ مِنَ الْمُسْلِمِينَ ‏.‏

Muhammad b. al-Hanafiyyah said: I said to my father: Which of the people after the Messenger of Allah (PBUH) is best? He replied: Abu Bakr. I then asked: Who comes next? He said: ‘Umar. I was then afraid of asking him who came next, and he might mention ‘Uthman, so I said: You came next, O my father? He said: I am only a man among the Muslims. Translation Not Available
