It is narrated from Sayyiduna Abdullah bin Salam (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "I am the leader of the children of Adam on the Day of Resurrection, and (I say this) not as a boast; I am the first for whom the earth will split open, and (this too is) not as a boast; and I am the first to intercede and the one whose intercession will be accepted. On the Day of Resurrection the Banner of Praise will be in my hand; beneath me will be Adam and all those below him."
