If anyone is killed. Ibn 'Ubaid in his version said: The Messenger of Allah ﷺ said: If anyone is killed in error (blindly) when people are throwing stones, or by beating with whips, or striking with a stick, it is accidental and the compensation for accidental death is due. But if anyone is killed deliberately, retaliation is due. Ibn 'Ubaid in his version: Retaliation of the man is due. The agreed version then goes: If anyone comes in (between the two parties) to prevent it, Allah's curse and anger will rest on him, and neither supererogatory nor obligatory acts will be accepted from him. The version of the tradition of Sufyan is more perfect.  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ قُتِلَ فِي عِمِّيَّا فِي رَمْىٍ يَكُونُ بَيْنَهُمْ بِحِجَارَةٍ أَوْ ضَرْبٍ بِالسِّيَاطِ أَوْ ضَرْبٍ بِعَصًا فَهُوَ خَطَأٌ وَعَقْلُهُ عَقْلُ الْخَطَإِ وَمَنْ قُتِلَ عَمْدًا فَهُوَ قَوَدٌ وَقَالَ ابْنُ عُبَيْدٍ قَوَدُ يَدٍ ثُمَّ اتَّفَقَا وَمَنْ حَالَ دُونَهُ فَعَلَيْهِ لَعْنَةُ اللَّهِ وَغَضَبُهُ لاَ يُقْبَلُ مِنْهُ صَرْفٌ وَلاَ عَدْلٌ وَحَدِيثُ سُفْيَانَ أَتَمُّ  

The Messenger of Allah ﷺ as saying: He then mentioned the rest of the tradition to the same effect as mentioned by Sufyan.  

قَالَ رَسُولُ اللَّهِ ﷺ فَذَكَرَ مَعْنَى حَدِيثِ سُفْيَانَ
