Is it obligatory for someone born of rape to carry the name of the rapist father, or is it permissible for him to change his name and be attributed to another name?

If a woman becomes pregnant from fornication or rape, and the man does not marry her during her pregnancy, the child is not attributed to him by consensus. If he marries her during her pregnancy, the majority of scholars do not attribute the child to him, while some scholars permit it.

Based on this, if the man did not marry your mother during her pregnancy with you, it is not permissible for you to be attributed to him. You should choose a common name for yourself, and your lineage is solely through your mother. However, if he married her during her pregnancy and you need to be attributed to him, you may follow the opinion of those who permitted it; otherwise, you should not be attributed to him.
