What are the Islamic rules on adoption?

“The law of Islam is that the adopted child be attributed to his biological parents. Attributing the adopted child to the adoptive parents and regarding them to be his real parents is not permissible. Hence, if it is possible for you to change your ID, then you should do so.”

“In terms of Shar’ie Law, it is not permissible to give an adopted child the surname of the foster parent/father. The adopted child will hold the surname of his real parent as instructed in the Quraan Sharif in Surah Ahzaab;”

“As-salaamu `alaykum wa-ramatullahi wa-barakatuh. It is permissible to adopt a child. Rasulullah ﷺ had also adopted Zaid bin Haaritha (Radi allahu anhu). It was a norm amongst the Sahaba (Radi allahu anhum) to adopt orphan children of other Sahaba who became martyred in the path of Allah.”

“It is permissible for adopted children to discharge their Zakaat by giving it to their adoptive parents and vice versa. This is subject to the condition that they are eligible recipients of Zakaat.”
