Is expiation obligatory for someone who swore not to permit his wife to buy summer clothes except in summer, then permitted her before summer officially began due to rising temperatures and people's need for summer clothes? And is it permissible for him to fast as expiation if it becomes obligatory, given that he does not possess enough to feed or clothe?
If the swearer intended by his oath that his wife should not buy summer clothes except when she needs them, and she bought them when she needed them, then there is nothing upon him nor any expiation, even if his estimation of the time for summer to begin was incorrect, because an oath is based on the intention of the swearer.
