Sayyiduna Abu Umamah (may Allah be pleased with him) narrated: We went out with the Messenger of Allah (peace and blessings be upon him), and the strap of his sandal broke. He (peace and blessings be upon him) said: "Inna lillahi wa inna ilayhi raji'un (We belong to Allah and to Him we return)." A man said: This is only a strap. The Messenger of Allah (peace and blessings be upon him) said: "It too is an affliction."
