Sayyiduna Jabir (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "The keys of the world were presented to me placed on a piebald horse (one whose colouring is black and white), on which there was a cloth made of sundus (fine silk)."
Imam Ahmad recorded this narration, and its narrators are the narrators of the Sahih.
