Under Egyptian Personal Status law, although the father is considered to be the guardian of his children, the mother has the right to custody of both male and female children until they reach fifteen years of age. This is applied even if the mother is foreign and intends to take the children out of the country.
The mother kept demanding more, however.
At one time, she made a video of her beating the child. In a short clip, the boy’s skinny body appears, his tears overflowing as he was severely beaten by a woman asking him in a loud voice to call his father, “Say, come, take me .. the spirit of living with him threw you like a dog.” It seems the threat was to pay more, or to see his son beaten.
