Question: I received a question from one of the employees in the identity card department stating that the people who newly embrace Islaam sometimes need to change their names especially if their meaning contradict Islaamic beliefs.It sometimes happens that some of them apostatize from Islaam. This requires the re-changing of their names again to the previous ones before Islaam. There are many Islaamic and non-Islaamic rulings that are dependent upon these changes like inheritance, marriage and personal status. Now, since the person asking this question works in the Civil Affairs Department, Identity Card Branch, will he be committing a sin if he changes the names of such persons?
