'Amro bin Shu'aib narrated on the authority of his father, on the authority of his grandfather (RAA) that the Messenger of Allah (ﷺ) said:
“The Diyah of the quasi-deliberate homicide is as severe as deliberate murder (in its being given in three types of camels), and the offender is not to be killed. This happens when the devil excites enmity between people causing them to shed blood but not due to hatred or carrying weapons in fighting.” Related by Ad-Daraqutni and graded it as weak Hadith.
وَعَنْهُ قَالَ: قَالَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-{ عَقْلُ شِبْهِ اَلْعَمْدِ مُغَلَّظٌ مِثْلُ عَقْلِ اَلْعَمْدِ, وَلَا يَقْتَلُ صَاحِبُهُ, وَذَلِكَ أَنْ يَنْزُوَ اَلشَّيْطَانُ, فَتَكُونُ دِمَاءٌ بَيْنَ اَلنَّاسِ فِي غَيْرِ ضَغِينَةٍ, وَلَا حَمْلِ سِلَاحٍ }  أَخْرَجَهُ اَلدَّارَقُطْنِيُّ وَضَعَّفَهُ  1‏‏1 ‏- حسن.‏ رواه الدارقطني (3/95)‏، وهو أيضا عند أبي داود (4565)‏، ولم أجد تضعيف الدارقطني في "السنن" وعلى أية حال الحديث سنده حسن، ولا توجد حجة لتضعيفه.‏
