What did the Prophet Muhammad (peace be upon him) tell the people in the cave after the snake escaped their attempt to kill it?
 Narrated `Abdullah:                     Once we were in the company of Allah's Apostle in a cave. Surat-al-Mursalat (77) was revealed there, and we were learning it from Allah's Apostle . Suddenly a snake came out of its hole and we rushed towards it to kill it, but it hastened and entered its hole before we were able to catch it. Allah's Apostle said," It has been saved from your evil and you have been saved from its evil."
