Sahih al-Bukhari 3534
Narrated Jabir bin `Abdullah:
The Prophet (ﷺ) said, "My similitude in comparison with the other prophets is that of a man who has built 
a house completely and excellently except for a place of one brick. When the people enter the house, 
they admire its beauty and say: 'But for the place of this brick (how splendid the house will be)!"
حَدَّثَنَا مُحَمَّدُ بْنُ سِنَانٍ، حَدَّثَنَا سَلِيمٌ، حَدَّثَنَا سَعِيدُ بْنُ مِينَاءَ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ ـ رضى الله عنهما ـ قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏
"‏ مَثَلِي وَمَثَلُ الأَنْبِيَاءِ كَرَجُلٍ بَنَى دَارًا فَأَكْمَلَهَا وَأَحْسَنَهَا، إِلاَّ مَوْضِعَ لَبِنَةٍ، فَجَعَلَ النَّاسُ يَدْخُلُونَهَا وَيَتَعَجَّبُونَ، وَيَقُولُونَ لَوْلاَ مَوْضِعُ اللَّبِنَةِ ‏"‏‏.‏
