It is narrated from Sayyiduna Jarud (may Allah be pleased with him) that he said: We were on an emaciated camel, and we came to the Messenger of Allah (peace and blessings be upon him) and said: "O Messenger of Allah (peace and blessings be upon him), we passed by al-Juruf and found a camel there, so we rode it." He (peace and blessings be upon him) said: "The stray property of a Muslim is an ember of the Fire."
