Al-Murin Al-Qatab and the Nightmare

Al-Murin al-Qatab was going to kill the Prophet sah-i-sallat-a-man. When he knocked on Dhar al-Arqam's door, a man looked out and saw him with his sword. Hamz-al-Lah-an-hah immediately panics when he realized who it was. He grabbed al-Murin by both of his hands and brought him to his knees. The prophet said: "Are you not going to stop until Allah sends a lightning bolt"
