Appointing an ameer (leader)
Question

                What is the ruling on appointing someone
      as an ameer when not travelling, such as when a group of young men are sharing a flat or
      in a camp that is held within the city or elsewhere?
Praise be to Allah.The reports that have been narrated concerning
    appointing an ameer refer specifically to when people are travelling, because when people
    are travelling they need to be able to refer their opinions to a leader or ameer. But when
    people are not travelling, usually each individual is busy with his own affairs and they
    do not need an ameer.
But they may appoint someone to be the head of their society or group,
    so if for example they are living in a flat, they may say” we need someone to
    organize our affairs in this flat, so we will appoint So and so to be our head or
    ameer.” Then they can discuss with him the running of this household’s affairs,
    such as what kind of food to have, setting times of rest, deciding what needs to be
    bought, and so on, so they discuss these things with him and agree to accept what he says.
    This is correct, in sha Allaah.
