What is the ruling on adopting an orphaned child from Algeria and bringing him to France, given that French laws require him to be registered in the family record book and under one's name, which contradicts the ruling on adoption in Islam?

Adoption is forbidden. However, a child can be sponsored by providing for their expenses, raising them, and guiding them, without taking them in for residency. This is due to the potential harms that could result, such as compelling the child to be attributed to you, especially since residing in non-Muslim lands poses serious dangers for children.
