Narrated Jabir bin 'Abdullah: The Prophet 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)!"
— Sahih Bukhari, Volume 4, Book 56: Virtues and Merits of the Prophet (pbuh) and his Companions, Hadith #734
