[Machine] From the ship of the master of the Messenger of Allah ﷺ , it is narrated that when the Messenger of Allah ﷺ built the mosque, Abu Bakr came with a stone and placed it, then Umar came with a stone and placed it, then Uthman came with a stone and placed it. The Messenger of Allah ﷺ said, "These are the leaders after me." This is an authentic Hadith with a sound chain of narration, and it was not narrated by Sahih.
