On his father's authority, said that his grandfather reported the Prophet ﷺ said: Blood-wit for what resembles intentional murder is to be made as severe as that for intentional murder, but the culprit is not to be killed. Khalid gave us some additional information on the authority of Ibn Rashid: That (unintentional murder which resembles intentional murder) means that Satan jumps among the people and then the blood is shed blindly without any malice and weapon. (Using translation from Abū Dāʾūd 4565)

أَنَّ رَسُولَ اللهِ ﷺ قَالَ عَقْلُ شِبْهِ الْعَمْدِ مُغَلَّظٌ مِثْلُ عَقْلِ الْعَمْدِ وَلَا يُقْتَلُ صَاحِبُهُ وَذَلِكَ أَنْ يَنْزُوَ الشَّيْطَانُ بَيْنَ النَّاسِ قَالَ أَبُو النَّضْرِ فَيَكُونُ رِمِّيًّا فِي عِمِّيًّا فِي غَيْرِ فِتْنَةٍ وَلَاحَمْلِ سِلَاحٍ

[Machine] The Messenger of Allah ﷺ said, "The liability for harmful acts caused by things (such as throwing stones) is strict and the owner of the thing causing harm is not to be killed. This is because Satan may hide among a group, so stoning may occur between them unintentionally, without animosity or intention to harm, and without carrying a weapon."

أَنَّ رَسُولَ اللهِ ﷺ قَالَ شِبْهُ الْعَمْدِ مُغَلَّظَةٌ وَلَا يُقْتَلُ بِهِ صَاحِبُهُ وَذَلِكَ أَنْ يَنْزُوَ الشَّيْطَانُ بَيْنَ الْقَبِيلَةِ فَيَكُونُ بَيْنَهُمْ رِمِّيَّا بِالْحِجَارَةِ فِي عِمِّيَّا فِي غَيْرِ ضَغِينَةٍ وَلَا حَمْلِ سِلَاحٍ
