Musnad Ahmad 28:26

Abu Mu'awiyah narrated to us, Al-A'mash narrated to us, from Abu as-Safar, from Abdullah ibn Amr ibn al-Aas, who said: The Messenger of Allah (peace and blessings of Allah be upon him) passed by us while we were repairing a hut of ours. He said, "What is this?" We said, "A hut of ours that is dilapidated, so we are repairing it." He said, "Verily, the matter is more urgent than that."
