It is narrated from Sayyiduna al-Mustawrid bin Shaddad (may Allah be pleased with him); he said: I heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever becomes an official for us, let him acquire a wife; if he has no servant, let him acquire a servant; and whoever has no dwelling, let him acquire a dwelling."
