It was narrated from Abu Ubaidah that his father said:

"We were with the Messenger of Allah on the night of Arafat which is before Arafat, when he heard a snake. The Messenger of Allah said: 'Kill it.' It went into a crack in a rock, and we put a stick in and broke part of the hole, then we took some palm tree leave and set them ablaze in the hole. The Messenger of Allah: 'Allah protected it from your evil and protected you from its evil.'"

أَخْبَرَنَا عَمْرُو بْنُ عَلِيٍّ، قَالَ حَدَّثَنَا يَحْيَى، قَالَ حَدَّثَنَا ابْنُ جُرَيْجٍ، أَخْبَرَنِي أَبُو الزُّبَيْرِ، عَنْ مُجَاهِدٍ، عَنْ أَبِي عُبَيْدَةَ، عَنْ أَبِيهِ، قَالَ كُنَّا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم لَيْلَةَ عَرَفَةَ الَّتِي قَبْلَ يَوْمِ عَرَفَةَ فَإِذَا حِسُّ الْحَيَّةِ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ اقْتُلُوهَا ‏"‏ ‏.‏ فَدَخَلَتْ شَقَّ جُحْرٍ فَأَدْخَلْنَا عُودًا فَقَلَعْنَا بَعْضَ الْجُحْرِ فَأَخَذْنَا سَعَفَةً فَأَضْرَمْنَا فِيهَا نَارًا فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ وَقَاهَا اللَّهُ شَرَّكُمْ وَوَقَاكُمْ شَرَّهَا ‏"‏ ‏.‏
