The Messenger of Allah ﷺ said, "My likeness among the prophets is like that of a man who built a house, perfecting it, completing it, and beautifying it, but he left in it the space of a single brick. People began to walk around the building, marveling at it and saying, 'If only the space of that brick were filled.' I am, among the prophets, the place of that brick."By the same chain of narration, the Prophet ﷺ said, "On the Day of Resurrection, I shall be the leader of the prophets, their spokesman, and the one who intercedes for them, and I say this without boasting."
حدثنا محمد بن بشار حدثنا أبو عامر العقدي حدثنا زهير بن محمد عن عبد الله بن محمد بن عقيل
أن رسول الله ﷺ قال مثلي في النبيين كمثل رجل بنى دارا فأحسنها وأكملها وأجملها وترك منها موضع لبنة فجعل الناس يطوفون بالبناء ويعجبون منه ويقولون لو تم موضع تلك اللبنة وأنا في النبيين موضع تلك اللبنة وبهذا الإسناد عن النبي ﷺ قال إذا كان يوم القيامة كنت إمام النبيين وخطيبهم وصاحب شفاعتهم غير فخر
[Hasan] Ahmad narrated it, 5/136, from Abu Amir Aqadi with the same wording. Ibn Majah also narrated it, no. 4314, from the hadith of Ibn Aqeel with the same wording, in abridged form. Hakim graded it sahih, 1/71 and 4/78, and Dhahabi agreed with him. The hadith has corroborating narrations, see no. 2862.
