It was narrated from Ibn Abu Rafi’, from his father, from his grandfather, that the Prophet (ﷺ) killed a scorpion while he was praying.
حَدَّثَنَا مُحَمَّدُ بْنُ يَحْيَى، حَدَّثَنَا الْهَيْثَمُ بْنُ جَمِيلٍ، حَدَّثَنَا مَنْدَلٌ، عَنِ ابْنِ أَبِي رَافِعٍ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، أَنَّ النَّبِيَّ ـ صلى الله عليه وسلم ـ قَتَلَ عَقْرَبًا وَهُوَ فِي الصَّلاَةِ .
