Abdur-Rahman bin Jubayr bin Nufayr said: I was in a gathering in which Sayyiduna al-Mustawrid bin Shaddad (may Allah be pleased with him) and Amr bin Ghaylan were present, and I heard Sayyiduna al-Mustawrid (may Allah be pleased with him) say: I heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever takes charge of some work for us and has no wife, let him marry; or has no servant, let him take a servant; or has no dwelling, let him get a dwelling; or has no mount, let him take a mount. Whoever obtains anything besides that is a misappropriator or a thief."
