The Statement of Allah the Most High: "That will be a Day when they shall not speak (during some part of it) ." (V.77:35)
Narrated `Abdullah:
While we were with the Prophet (ﷺ) in a cave, Surat wal-Mursalat was revealed to him 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, "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."
