Imam Ahmad recorded that Abu Sa`id Al-Khudri, may Allah be pleased with him, said that the Messenger of Allah said:

«مَثَلِي وَمَثَلُ الْأَنْبِيَاءِ مِنْ قَبْلِي كَمَثَلِ رَجُلٍ بَنَى دَارًا فَأَتَمَّهَا إِلَّا مَوْضِعَ لَبِنَةٍ وَاحِدَةٍ، فَجِئْتُ أَنَا فَأَتْمَمْتُ تِلْكَ اللَّبِنَة»

(The parable of myself and the Prophets who came before me is that of a man who built a house and completed it apart from the space of one brick. I have come and completed that brick.) It was also recorded by Muslim.
