Sahih Adab al-Mufrad

It is narrated from Sayyiduna Abdullah bin Amr, may Allah be pleased with him, who says that the Prophet, peace and blessings be upon him, passed by while I was repairing my room. The Prophet, peace and blessings be upon him, asked: "What are you doing?" I said: O Messenger of Allah! I am repairing my room. He said: "The matter is even more urgent than this" (meaning death can come even more swiftly than this).
