Abu As-Safr narrated that 'Abdullah bin 'Amr said: "The Messenger of Allah (s.a.w) passed by us while we were repairing a hut of ours, so he said: 'What is this?' We said:"It has become weak, so we are repairing it.' He said: 'I do not think but that the matter (of life) is more in fleeting than that."
