Is it permissible to interrupt the prayer to revive a person who fainted while praying next to me?

It is permissible to interrupt a supererogatory prayer, though it is disliked, whereas it is not permissible to interrupt a fard (obligatory) prayer except out of necessity, such as saving an innocent person from perishing. In such a case, interrupting the prayer becomes obligatory if the person is feared to perish and needs to be rescued. However, if no harm would come to the person, then one must complete the prayer and then rescue them.
