It was narrated that ‘Aishah said: “The Prophet (ﷺ) was stung by a scorpion while he was performing prayer, and he said: ‘May Allah curse the scorpion, for it does not spare anyone, whether he is praying or not. Kill them whether you are in Ihram or not.’” In Al-Hill (outside the sacred precincts of Makkah) or Al-Haram (the sacred precincts or Makkah).
