Sayyiduna Abdullah (may Allah be pleased with him) narrates: Once we were with the Prophet Muhammad (peace and blessings be upon him) in a cave. Surah Mursalat was revealed to him. He recited it and I learned it from his tongue; it had been revealed to him just a short while before. Meanwhile, a snake appeared before us. The Prophet Muhammad (peace and blessings be upon him) said: Kill it! We quickly rushed towards it, but it went away. The Prophet Muhammad (peace and blessings be upon him) said: It has been saved from your harm just as you have been saved from its evil.
