The Messenger of Allah ﷺ said, "My example among the prophets is like a man who built a house, made it beautiful and complete, and adorned it, but left the place of one brick empty. People began walking around the building, marveling at it and saying, 'If only the place of that brick were filled.' I am, among the prophets, in the place of that brick."
أن رسول الله ﷺ قال: مثلي في النبيين كمثل رجل بني دارا فأحسنها وأكملها وجملها، وترك منها موضع لبنة، فجعل الناس يطوفون بالبناء، ويعجبون منه ويقولون: لو تم موضع تلك اللبنة، وأنا في النبيين بموضع تلك اللبنة.
Tirmidhi (3613) and Ahmad (21243) both narrated it via Abu Amir, who said, "Zuhayr bin Muhammad narrated to us, from Abdullah bin Muhammad bin Aqeel, from Tufayl bin Abu bin Kaab, from his father," and he related it. Tirmidhi said, "This is a hasan hadith."I say, it is as he said, for Abdullah bin Muhammad bin Aqeel is disputed, but his hadith is hasan.
