Is a mother entitled to the custody of her seven-year-old child after her divorce from the father three years ago, given that the father is aware of her misconduct and wishes to incorporate the child into his household?

Custody belongs to the mother as long as she does not remarry, and it ends when the boy reaches the age of seven. He is then given the choice between his parents, and whichever one he chooses, he stays with them, and the other parent is not prevented from visiting him. However, if the mother is not trustworthy due to immorality, he should not be handed over to her, and the father has a greater right to him if one of them travels a migratory journey. It is advisable to consult the Sharia court regarding matters of custody.
