Striking Stones to Make Fire
Interpreters mention that if one sees themselves striking a stone against another, causing fire to emerge, it may indicate a fierce fight between two harsh men, resulting in violence in their conflict. Some have said that striking a fire-steel might indicate Arab marriage. If the fire catches, it could signify the wife's pregnancy and the birth of a child between the spouses, or it might symbolize evil between them or between two adversaries or partners.
