Marwan al-Asfar said: I saw Ibn ‘Umar make his camel kneel facing the qibla , then sit down and pass water in its direction, so I said, “Abu ‘Abd ar-Rahman, [Ibn ‘Umar's kunya ] has this not been forbidden?” He replied, “No, that was forbidden only in open country; but when there is something between you and the qibla to conceal you, there is no harm.” Abu Dawud transmitted it.
