Sahih Muslim · Hadith 6103
The Book Pertaining to the Excellent Qualities of the Holy Prophet (may Peace be upon them) and His - كتاب الفضائل
حدثنا أبو بكر بن أبي شيبة، حدثنا عفان، حدثنا سليم بن حيان، حدثنا سعيد، بن ميناء عن جابر، عن النبي صلى الله عليه وسلم قال " مثلي ومثل الأنبياء كمثل رجل بنى دارا فأتمها وأكملها إلا موضع لبنة فجعل الناس يدخلونها ويتعجبون منها ويقولون لولا موضع اللبنة " . قال رسول الله صلى الله عليه وسلم " فأنا موضع اللبنة جئت فختمت الأنبياء " .
Jabir reported Allah's Messenger (may peace be upon him) as saying: The similitude of mine and that of the Apostles is like that of a person who built a house and he completed it and made it perfect but for the space of a brick. People entered therein and they were surprised at it and said: Had there been a brick (it would have been complete in all respects). Allah's Messenger (may peace be upon him) said: I am that place where the brick (completing the building is to be placed), and I have come to finalise the chain of Apostles.
