Attributing the illegitimate child

Q: I have a 50 year-old sister who was a born deaf-mute. During her youth, she had a relationship with a man and got pregnant then gave birth to a boy. When the boy was at school age, they refused to accept him until he submits his father's ID. I added him to my sons in my ID to let him enter school. Now he is in the third year of the secondary school and has memorized 15 Juz' (a 30th of the Qur'an). I wish to know from you the ruling on this issue. Should I keep him added to my ID card, bearing my name and inheriting with my children?

A: You must not attribute this boy to yourself and you have to remove him from your ID card. You should issue him a separate ID card and the father's and grandfather's names are any of Allah's Names such as `Abdullah, `Abd Al-Rahman and the like. The family name should be derived from the Region he was born in. Take this name as an example: Muhammad ibn `Abdullah ibn `Abd Al-Majid and the family name is Al-Ta'ify, Al-Madany, Al-Makky or the like. (Part No. 16; Page No. 15) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
