If parents fight infront of the children, what should be the children's stance?

Sheikh Muḥammad Al-’Ansi ḥafidhahullāh: The stance of children towards their mother and father should be that of peacemakers and not spectators of abuse. This (the latter) is not good. Likewise, [it's not good that when] the father starts beating [the mother] that the children join in and beat their father...likewise, taking sides is not permissible because Allāh said: {وَبِٱلۡوَ ٰ⁠لِدَیۡنِ إِحۡسَـٰنًا} “And be dutiful to your parents.” [Sūrah Al-Isrāʾ: 23] So it's necessary to be dutiful to both the father and the mother. It is not permissible to harm either one. If you are fanatical to your mother as a son (particularly), this will probably offend your father, and vice versa. This is why one avoids offending them [by taking sides]. May Allāh bless you. Rather, act as peacemakers. I mean, resolve the matter with your father using good words, and the same with your mother, so that it does not re-occur. For example, perhaps your mother opposes and disagrees with your father, which leads him to get all worked up & angry, and so he starts hitting her because of this, or perhaps he is like this; he hits her without any reason. The point being, the problem should be resolved without being fanatical to any side. The mother has brothers, she has a family, she has her guardians. If the situation escalates beyond control, she can involve her guardians to help solve it. People like her father, uncle, brother, uncle, cousin, etc. from among her guardians. They look into this problem according to what Allāh, Blessed is He, says: { وَإِنۡ خِفۡتُمۡ شِقَاقَ بَیۡنِهِمَا فَٱبۡعَثُوا۟ حَكَمࣰا مِّنۡ أَهۡلِهِۦ وَحَكَمࣰا مِّنۡ أَهۡلِهَاۤ إِن یُرِیدَاۤ إِصۡلَـٰحࣰا یُوَفِّقِ ٱللَّهُ بَیۡنَهُمَاۤۗ} “If you anticipate a split between them, appoint a mediator from his family and another from hers. If they desire reconciliation, Allāh will restore harmony between them.” [Sūrah An-Nisāʾ: 35] And Allāh Almighty said: {وَإِنِ ٱمۡرَأَةٌ خَافَتۡ مِنۢ بَعۡلِهَا نُشُوزًا أَوۡ إِعۡرَاضࣰا فَلَا جُنَاحَ عَلَیۡهِمَاۤ أَن یُصۡلِحَا بَیۡنَهُمَا صُلۡحࣰاۚ وَٱلصُّلۡحُ خَیۡرࣱ} “If a woman fears indifference or neglect from her husband, there is no blame on either of them if they seek ˹fair˺ settlement, which is best.” [Sūrah An-Nisāʾ: 128] We seek Allāh's help.
