The Prophet ﷺ said, "My example and the example of the prophets before me is like a man who built a house, completing it beautifully except for the place of one brick. People would enter it, marvel at it, and say, 'If only this brick were in its place!'"
قال النبي ﷺ: مثلي ومثل الأنبياء كرجل بنى دارا فأكملها وأحسنها إلا موضع لبنة، فجعل الناس يدخلونها ويتعجبون ويقولون: لولا موضع اللبنة.
Bukhari narrated it in Manaqib (3534), and Muslim in Fadail, both from the hadith of Salim bin Hayan, who said, "Saeed bin Mina told us, from Jabir bin Abdullah," and he related it.
