Is an expiation for an oath (kaffarat yameen) obligatory for someone who swore that his mother would not close the door on the child, and then the mother placed her in the same spot without closing the door, and is what the mother said correct, that the oath is not binding as long as the condition upon which the oath was built has not been fulfilled?

If a person swears that his mother will not put the girl in a specific place, and his oath includes both the case of the door being closed and not being closed, then expiation is due. However, if his intention was to specify the oath only to the case where the door is closed, or if placing the girl without closing the door does not cause her fright (which was the reason for the oath), then he does not break his oath. The intention of the swearer or the reason for the oath specifies the general wording if no intention exists.
