It was narrated from Abu Hurairah that the Prophet ﷺ commanded killing the two black ones during prayer; the scorpion and the snake.  

أَنَّ النَّبِيَّ ﷺ أَمَرَ بِقَتْلِ الأَسْوَدَيْنِ فِي الصَّلاَةِ الْعَقْرَبِ وَالْحَيَّةِ  

“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).  

لَدَغَتِ النَّبِيَّ ﷺ عَقْرَبٌ وَهُوَ فِي الصَّلاَةِ فَقَالَ لَعَنَ اللَّهُ الْعَقْرَبَ مَا تَدَعُ الْمُصَلِّيَ وَغَيْرَ الْمُصَلِّي اقْتُلُوهَا فِي الْحِلِّ وَالْحَرَمِ  

It was narrated from Ibn Abu Rafi’, from his father, from his grandfather, that the Prophet ﷺ killed a scorpion while he was praying.  

أَنَّ النَّبِيَّ ﷺ قَتَلَ عَقْرَبًا وَهُوَ فِي الصَّلاَةِ
