Jami` at-Tirmidhi 3613
Narrated At-Tufail bin Ubayy bin Ka'b:
from his father that the Messenger of Allah (ﷺ) said: "The parable of me and the Prophets is that of a man who built a house, and he built it well, completing it, and beautifying it, but he left a space for one brick. So the people began going around the house amazed at it, saying "If only the space for that brick was filled.' And I am, with regards to the Prophets, in the position of that brick."
And with this chain, from the Prophet (ﷺ) that he said: "Upon the Day of Judgement I will be the leader of the Prophets and their spokesman, and the bearer of their intercession, without bragging."
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا أَبُو عَامِرٍ الْعَقَدِيُّ، حَدَّثَنَا زُهَيْرُ بْنُ مُحَمَّدٍ، عَنْ عَبْدِ اللَّهِ بْنِ مُحَمَّدِ بْنِ عَقِيلٍ، عَنِ الطُّفَيْلِ بْنِ أُبَىِّ بْنِ كَعْبٍ، عَنْ أَبِيهِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ مَثَلِي فِي النَّبِيِّينَ كَمَثَلِ رَجُلٍ بَنَى دَارًا فَأَحْسَنَهَا وَأَكْمَلَهَا وَأَجْمَلَهَا وَتَرَكَ مِنْهَا مَوْضِعَ لَبِنَةٍ فَجَعَلَ النَّاسُ يَطُوفُونَ بِالْبِنَاءِ وَيَعْجَبُونَ مِنْهُ وَيَقُولُونَ لَوْ تَمَّ مَوْضِعُ تِلْكَ اللَّبِنَةِ وَأَنَا فِي النَّبِيِّينَ مَوْضِعُ تِلْكَ اللَّبِنَةِ ‏"‏ ‏.‏   

 وَبِهَذَا الإِسْنَادِ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏ إِذَا كَانَ يَوْمُ الْقِيَامَةِ كُنْتُ إِمَامَ النَّبِيِّينَ وَخَطِيبَهُمْ وَصَاحِبَ شَفَاعَتِهِمْ غَيْرُ فَخْرٍ ‏"‏ ‏.‏ قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ غَرِيبٌ ‏.‏
