Adek , yo do make me laugh
please learn something about Ottoman and Mogul empires in turkey and India , both Islamic
the brothers killed each other’s and imprisoned their fathers for life , it’s a regular affair and accepted too
in the ottoman Islamic empire when a brother accents the throne her own mother would encourage the elimination of the rest of her male children even where there was no challenge to the throne itself ,and these were the children growing up together sharing the same meal and the comfort of the same mother
in a classical case ,the Sha Jahan built the Taj Mahal but his own son imprisoned him for the rest of his life dying a broken man , and they are Islamic empire that ruled India
