Sayyiduna Anas bin Malik (may Allah be pleased with him) says: The Messenger of Allah (peace and blessings be upon him) sent Busaysah as a scout to observe the movements of Abu Sufyan's caravan. The narrator says: When he came, there was no one in the house except me and the Messenger of Allah (peace and blessings be upon him). Then he related the account.
