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)!"  

قَالَ النَّبِيُّ ﷺ مَثَلِي وَمَثَلُ الأَنْبِيَاءِ كَرَجُلٍ بَنَى دَارًا فَأَكْمَلَهَا وَأَحْسَنَهَا إِلاَّ مَوْضِعَ لَبِنَةٍ فَجَعَلَ النَّاسُ يَدْخُلُونَهَا وَيَتَعَجَّبُونَ وَيَقُولُونَ لَوْلاَ مَوْضِعُ اللَّبِنَةِ  

Messenger of Allah ﷺ said, "My similitude in comparison with the other prophets before me, is that of a man who has built a house nicely and beautifully, except for a place of one brick in a corner. The people go about it and wonder at its beauty, but say: 'Would that this brick be put in its place!' So I am that brick, and I am the last of the Prophets."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِنَّ مَثَلِي وَمَثَلَ الأَنْبِيَاءِ مِنْ قَبْلِي كَمَثَلِ رَجُلٍ بَنَى بَيْتًا فَأَحْسَنَهُ وَأَجْمَلَهُ إِلاَّ مَوْضِعَ لَبِنَةٍ مِنْ زَاوِيَةٍ فَجَعَلَ النَّاسُ يَطُوفُونَ بِهِ وَيَعْجَبُونَ لَهُ وَيَقُولُونَ هَلاَّ وُضِعَتْ هَذِهِ اللَّبِنَةُ قَالَ فَأَنَا اللَّبِنَةُ وَأَنَا خَاتِمُ النَّبِيِّينَ
