باب صِفَةِ النَّبِيِّ صلى الله عليه وسلم
Sahih al-Bukhari 3567, 3568

Narrated `Aisha:

The Prophet (ﷺ) used to talk so clearly that if somebody wanted to count the number of his words, he could do so. Narrated `Urwa bin Az-Zubair: `Aisha said (to me), "Don't you wonder at Abu so-and-so who came and sat by my dwelling and started relating the traditions of Allah's Messenger (ﷺ) intending to let me hear that, while I was performing an optional prayer. He left before I finished my optional prayer. Had I found him still there. I would have said to him, 'Allah's Messenger (ﷺ) never talked so quickly and vaguely as you do.' "

حَدَّثَنِي الْحَسَنُ بْنُ صَبَّاحٍ الْبَزَّارُ، حَدَّثَنَا سُفْيَانُ، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ ـ رضى الله عنها أَنَّ النَّبِيَّ صلى الله عليه وسلم كَانَ يُحَدِّثُ حَدِيثًا لَوْ عَدَّهُ الْعَادُّ لأَحْصَاهُ‏.‏ وَقَالَ اللَّيْثُ حَدَّثَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، أَنَّهُ قَالَ أَخْبَرَنِي عُرْوَةُ بْنُ الزُّبَيْرِ، عَنْ عَائِشَةَ، أَنَّهَا قَالَتْ أَلاَ يُعْجِبُكَ أَبُو فُلاَنٍ جَاءَ فَجَلَسَ إِلَى جَانِبِ حُجْرَتِي يُحَدِّثُ عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم، يُسْمِعُنِي ذَلِكَ وَكُنْتُ أُسَبِّحُ فَقَامَ قَبْلَ أَنْ أَقْضِيَ سُبْحَتِي، وَلَوْ أَدْرَكْتُهُ لَرَدَدْتُ عَلَيْهِ، إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم لَمْ يَكُنْ يَسْرُدُ الْحَدِيثَ كَسَرْدِكُمْ‏.‏
