Fire Emitting from Body Parts
Scholars have said that whoever sees fire coming out of their finger, it may indicate that they are an unjust scribe. If it comes out of their mouth, they might be a slanderer. If it comes out of their palm, they are an unjust craftsman. As for whoever kindles a fire in a ruin and invites people to it, they may be inviting them to error and innovation.
