What was the reaction of the grocers after they witnessed Baba light the lamps with water?

After lying to Baba and refusing him oil, the grocers watched to see what he would do. When they saw the lamps burn brightly with water, Chapter 5 states they were so amazed they 'put their fingers in their mouths.' They immediately felt repentance, realizing they had sinned by speaking an untruth and giving Baba needless trouble. The text mentions that as the lamps burned all night without a drop of oil, these 'unworthy' grocers began to tremble, fully comprehending the divine power they had just witnessed.
