(7) باب مَا يَقْتُلُ الْمُحْرِمُ مِنَ الدَّوَابِّ
Narrated `Abdullah:
While we were in the company of the Prophet (ﷺ) in a cave at Mina, when Surat-wal-Mursalat were revealed and he recited it and I heard it (directly) from his mouth as soon as he recited its revelation. Suddenly a snake sprang at us and the Prophet (ﷺ) said (ordered us): "Kill it." We ran to kill it but it escaped quickly. The Prophet (ﷺ) said, "It has escaped your evil and you too have escaped its evil."
