عن أبي هريرة رضي الله عنه قال: قال رسول الله صلى الله عليه وسلم : «اقتلوا الأسودَين في الصلاة: الحيَّة، والعقرب».
Abu Hurayrah (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "Kill the two blacks during prayer: the snake and the scorpion."
This noble Hadīth points out that killing snakes and scorpions even during prayer is recommendable, because we have been ordered to kill them, and because their killing requires a limited movement that does not invalidate prayer.
