Abu Huraira reported Allah's Messenger as saying: The similitude of mine and that of the Apostles (before me) is that of a person who constructed a building and he built it fine and well and the people went round it saying: Never have we seen a building more imposing than this. but for one brick, and I am that brick (with which you give the finishing touch to the building).

حَدَّثَنَا عَمْرُو بْنُ مُحَمَّدٍ النَّاقِدُ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏ "‏ مَثَلِي وَمَثَلُ الأَنْبِيَاءِ كَمَثَلِ رَجُلٍ بَنَى بُنْيَانًا فَأَحْسَنَهُ وَأَجْمَلَهُ فَجَعَلَ النَّاسُ يُطِيفُونَ بِهِ يَقُولُونَ مَا رَأَيْنَا بُنْيَانًا أَحْسَنَ مِنْ هَذَا إِلاَّ هَذِهِ اللَّبِنَةَ ‏.‏ فَكُنْتُ أَنَا تِلْكَ اللَّبِنَةَ ‏" ‏ ‏.‏
