Commentary 1قَالَ الْفَضْلُ بْنُ شَاذَانَ النَّيْسَابُورِيُّ لَوْ أَنَّ رَجُلًا ضَرَبَ ابْنَهُ ضَرْباً غَيْرَ مُسْرِفٍ فِي ذَلِكَ يُرِيدُ بِهِ تَأْدِيبَهُ فَمَاتَ الِابْنُ مِنْ ذَلِكَ الضَّرْبِ وَرِثَهُ الْأَبُ وَ لَمْ تَلْزَمْهُ الْكَفَّارَةُ لِأَنَّ لِلْأَبِ أَنْ يَفْعَلَ ذَلِكَ وَ هُوَ مَأْمُورٌ بِتَأْدِيبِ وَلَدِهِ لِأَنَّهُ فِي ذَلِكَ بِمَنْزِلَةِ الْإِمَامِ يُقِيمُ حَدّاً عَلَى رَجُلٍ فَيَمُوتُ الرَّجُلُ مِنْ ذَلِكَ الضَّرْبِ فَلَا دِيَةَ عَلَى الْإِمَامِ وَ لَا كَفَّارَةَ وَ لَا يُسَمَّى الْإِمَامُ قَاتِلًا إِذَا أَقَامَ حَدَّ اللَّهِ عَزَّ وَ جَلَّ عَلَى رَجُلٍ فَمَاتَ مِنْ ذَلِكَ وَ إِنْ ضَرَبَ الِابْنَ ضَرْباً مُسْرِفاً فَمَاتَ لَمْ يَرِثْهُ الْأَبُ وَ كَانَتْ عَلَيْهِ الْكَفَّارَةُ وَ كُلُّ مَنْ كَانَ لَهُ الْمِيرَاثُ لَا كَفَّارَةَ عَلَيْهِ وَ كُلُّ مَنْ لَمْ يَكُنْ لَهُ الْمِيرَاثُ فَعَلَيْهِ الْكَفَّارَةُ فَإِنْ كَانَ بِالابْنِ جُرْحٌ فَبَطَّهُ الْأَبُ فَمَاتَ الِابْنُ مِنْ ذَلِكَ فَإِنَّ هَذَا لَيْسَ بِقَاتِلٍ وَ هُوَ يَرِثُهُ وَ لَا كَفَّارَةَ عَلَيْهِ وَ لَا دِيَةَ لِأَنَّ هَذَا بِمَنْزِلَةِ الْأَدَبِ وَ الِاسْتِصْلَاحِ وَ الْحَاجَةِ مِنَ الْوَلَدِ إِلَى ذَلِكَ وَ إِلَى شِبْهِهِ مِنَ الْمُعَالَجَاتِ وَ لَوْ أَنَّ رَجُلًا كَانَ رَاكِباً عَلَى دَابَّةٍ فَوَطِئَتْ أَبَاهُ أَوْ أَخَاهُ فَمَاتَ مِنْ ذَلِكَ لَمْ يَرِثْهُ وَ كَانَتِ الدِّيَةُ عَلَى الْعَاقِلَةِ وَ الْكَفَّارَةُ عَلَيْهِ وَ لَوْ كَانَ يَسُوقُ الدَّابَّةَ أَوْ يَقُودُهَا فَوَطِئَتْ أَبَاهُ أَوْ أَخَاهُ فَمَاتَ وَرِثَهُ وَ كَانَتِ الدِّيَةُ عَلَى الْعَاقِلَةِ لِلْوَرَثَةِ وَ لَمْ تَلْزَمْهُ كَفَّارَةٌ وَ لَوْ أَنَّ رَجُلًا حَفَرَ بِئْراً فِي غَيْرِ حَقِّهِ أَوْ أَخْرَجَ كَنِيفاً أَوْ ظُلَّةً فَأَصَابَ شَيْءٌ مِنْهَا وَارِثاً فَقَتَلَهُ لَمْ تَلْزَمْهُ الْكَفَّارَةُ وَ كَانَتِ الدِّيَةُ عَلَى الْعَاقِلَةِ وَ وَرِثَهُ لِأَنَّ هَذَا لَيْسَ بِقَاتِلٍ أَ لَا تَرَى أَنَّهُ إِنْ فَعَلَ ذَلِكَ فِي حَقِّهِ لَمْ يَكُنْ بِقَاتِلٍ وَ لَا وَجَبَ فِي ذَلِكَ دِيَةٌ وَ لَا كَفَّارَةٌ فَإِخْرَاجُهُ ذَلِكَ الشَّيْءَ فِي غَيْرِ حَقِّهِ لَيْسَ هُوَ قَتْلًا لِأَنَّ ذَلِكَ بِعَيْنِهِ يَكُونُ فِي حَقِّهِ فَلَا يَكُونُ قَتْلًا وَ إِنَّمَا أُلْزِمَ الْعَاقِلَةُ الدِّيَةَ فِي ذَلِكَ احْتِيَاطاً فِي الدِّمَاءِ وَ لِئَلَّا يَبْطُلَ دَمُ امْرِئٍ مُسْلِمٍ وَ لِئَلَّا يَتَعَدَّى النَّاسُ حُقُوقَهُمْ إِلَى مَا لَا حَقَّ لَهُمْ فِيهِ وَ كَذَلِكَ الصَّبِيُّ إِذَا لَمْ يُدْرِكْ وَ الْمَجْنُونُ لَوْ قَتَلَا لَوَرِثَا وَ كَانَتِ الدِّيَةُ عَلَى عَاقِلَتِهِمَا وَ الْقَاتِلُ يَحْجُبُ وَ إِنْ لَمْ يَرِثْ أَ لَا تَرَى أَنَّ الْإِخْوَةَ يَحْجُبُونَ الْأُمَّ وَ لَا يَرِثُونَ.
Al-Fadl ibn Shadhan Al-Naysaburi said: If a man strikes his son with a non-excessive blow intending to discipline him, and the son dies as a result of that strike, the father inherits from him and is not obligated to offer kaffarah (expiation). This is because the father has the right to discipline his child, and he is commanded to do so. In this case, the father is in the position of an Imam who enforces a legal punishment on a man, and if the man dies due to that punishment, there is no diyyah (blood money) or kaffarah upon the Imam, nor is the Imam considered a killer when he enforces the command of Allah (swt), the Mighty and Majestic. However, if the father strikes his son excessively and the son dies, the father does not inherit from him, and kaffarah becomes obligatory upon him. Anyone who is entitled to inherit does not bear kaffarah, but anyone who is not entitled to inherit must offer kaffarah. If the son had a wound and the father opened it (to treat it), and the son died from that, the father is not considered a killer. He inherits from his son, and there is neither kaffarah nor diyyah upon him because this action is regarded as a form of discipline, correction, and necessary treatment required for the child. If a man was riding an animal and it trampled over his father or brother, causing their death, he would not inherit from them. In this case, the diyyah (blood money) would be upon the Aqilah (the male relatives responsible for blood money), and the kaffarah (expiation) would be obligatory upon him. However, if he was leading or guiding the animal and it trampled over his father or brother, causing their death, he would inherit from them, the diyyah would still be upon the Aqilah for the heirs, and no kaffarah would be required from him. If a man dug a well in a place where he had no right to do so, or he opened a sewage channel or built a canopy, and one of his heirs was harmed by it and died, the man would not be liable for kaffarah, and the diyyah would be upon the Aqilah, and he would still inherit from the deceased. This is because he is not considered a killer. Do you not see that if he had done such things within his rightful property, he would not be considered a killer, and no diyyah or kaffarah would be required? Therefore, doing this in a place where he had no right is not considered intentional killing, as this action in his rightful place would not be deemed as such. The Aqilah is held responsible for the diyyah in this case as a precaution regarding the sanctity of life, to prevent the blood of a Muslim from being wasted, and to stop people from transgressing beyond their rights. Similarly, if a child who has not reached maturity or a mentally ill person committed a killing, they would still inherit, and the diyyah would be upon their Aqilah. Moreover, the killer prevents others from inheriting even if he himself does not inherit. Do you not see that siblings prevent the mother from inheriting a larger share, even though they themselves do not inherit in certain situations?
