What is the religious ruling regarding an abandoned girl who is rejected for marriage due to her unknown origins and lineage? Is what happened to her considered a sin? And how should she deal with people's negative talk and comments about her being an "abandoned child"? What is the ruling on hijab in front of her foster father and foster brother, or her brother through nursing? What is the ruling regarding the house and its contents after the death of her foster parents, knowing that the girl paid the greater part of its price? Is zakat obligatory on her brother's money, which she manages without his knowledge, and is she obliged to inform him about this money? What should the girl do about her brother's changing behavior, his irritability, and his use of bad language?

Before answering the questions, it must be noted that adoption is Islamically null and void. The adopted girl is considered a stranger to the man who sponsored her and to the boy she grew up with. Therefore, it is impermissible for her to be in seclusion with them, to shake their hands, or to see their awrah. It is also forbidden for her to attribute herself to them.

Regarding the questions, if the adopted girl possesses good character and religious devotion, men should not refrain from marrying her simply because she is a foundling; rather, religiosity is the criterion. Her not knowing her lineage is not a sin on her part, and Allah Almighty does not hold one soul accountable for the sin of another.

If the adopted girl paid more than two-thirds of the house's price with her own money and with proof, and it was agreed to register the house in her name and the boy's name equally, then the relatives of the deceased (the adoptive father) have no right to the house, but this must be documented.

It is impermissible to pay Zakat from the adopted boy's money except with his intention. If there is concern about his extravagance, the matter should be referred to the Shariah court or an Islamic center. If the money has reached the nisab, then he must pay its Zakat for all the past years. The adopted girl cannot reform the boy by herself because he is a stranger to her, and she should limit herself to supplicating for him or directing him through a message.
