Sahih Bukhari Volume 6, Book 65, Hadith 4932

حَدَّثَنَا مَحْمُودٌ، حَدَّثَنَا عُبَيْدُ اللَّهِ، عَنْ إِسْرَائِيلَ، عَنْ مَنْصُورٍ، عَنْ إِبْرَاهِيمَ، عَنْ عَلْقَمَةَ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ قَالَ كُنَّا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم وَأُنْزِلَتْ عَلَيْهِ وَالْمُرْسَلاَتِ، وَإِنَّا لَنَتَلَقَّاهَا مِنْ فِيهِ فَخَرَجَتْ حَيَّةٌ، فَابْتَدَرْنَاهَا فَسَبَقَتْنَا فَدَخَلَتْ جُحْرَهَا فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ وُقِيَتْ شَرَّكُمْ، كَمَا وُقِيتُمْ شَرَّهَا ‏"‏‏.‏

Narrated By Abdullah : We were with the Prophet when Surat Wal-Mursalat was revealed to him. While we were receiving it from his mouth, a snake suddenly came and we ran to kill it, but it outstripped us and entered its hole quickly. Allah's le said, "It has escaped your evil, and you too, have escaped its evil."
