This falls under the category of "Adoption".

Adopted sisters are not real sisters.

According to the Islamic law of prohibited marriages based on consanguinity and prohibited marriage partners, this relationship falls into the category of Halal or permitted.

In Islamic Shariah law, the term "sister" can refer to one of two relationships:

  1. Mahram (Non-Marriageable Kin): This includes your biological sisters, with whom marriage is strictly forbidden. The Quran explicitly mentions that marriage is not permitted with one's sisters in Surah An-Nisa (4:23).

  2. Non-Mahram (Marriageable Kin): If you refer to a woman as "sister" but she is not actually your biological or foster sister (i.e., she is not related to you by blood, breastfeeding, or adoption according to Islamic law), then she is not considered a mahram to you. In this case, it is generally permissible to marry her if all other conditions for a lawful marriage in Islam are met.
