Musnad Ahmad 3625

Abu ‘Ubaidah narrated that his father said: We were sitting in the mosque of al-Khaif on the night of Arafat, before the day of Arafat, when we heard the hissing of a snake. The Messenger of Allah (ﷺ) said: "Kill it.” we got up and it entered a crack in a rock. A palm branch was brought and fire was lit on it, and we took a stick and removed some of the rock, but we did not find it. The Messenger of Allah (ﷺ) said: "Let it be, Allah saved it from your mischief as He saved you from its mischief."
