The child abuse is cruelty
The child is innocent; the father works and toils in order to make child and family happy; so why all this cruelty?
The father is angry because he is very much tired and exhausted and want to have rest at home; he has right: but let him have more patience and forbearance and do not tread over the flower.
The father is struggling for the livelihood; he has right, then he sees the wife not cooperating or she betrays him; he has right and much right, but let not his anger and wrath be toward the innocent child and should not tread on the flower.
The father is tired and exhausted, and cannot withstand the overactivity of the child; so let the mother: the worker's wife be cooperative and instruct the child not to disturb his father; let her show him love and everything will be ok.
So forbear patiently, and have the required rest and love and the wife support the father in the face of life difficulties; but: for God's sake:
Don't tread over the innocent flower: the child.
(And that you slay not your children because of penury – We provide for you and for them.)

وَلاَ تَقْتُلُواْ أَوْلاَدَكُم مِّنْ إمْلاَقٍ نَّحْنُ نَرْزُقُكُمْ وَإِيَّاهُمْ
