What is the ruling on my ex-husband taking our six-year-old daughter, knowing that he used to take hashish, and I have no proof of his continued use, and in support of his claim, he demands that the child spend two weeks with him? So what is the solution?

After the separation of the spouses, custody belongs to the mother unless there is an impediment, and scholars differ on the age at which custody ends. If custody is with the mother, the father is not entitled to take his daughter to live with him except with the mother's consent. However, the custodian is not allowed to prevent the other party from seeing the child in custody. In case of dispute over visitation, the Sharia judge will rule on it. In case of dispute over custody or proving the father's فسق (immorality/unsuitability) to prevent him from having custody, recourse is made to the Sharia court.
