The ruling on taking money from the assistance provided to a mentally disabled daughter

The questioner : A woman asks: I am a woman who cares for a daughter of mine who suffers from mental impairment, and I look after her. She suffers from mental impairment and I look after her. The government, may Allah guide them, gives me seven thousand riyals annually to spend on her. Is it permissible for me to take some of it, given that I am her mother? And if I and her father are with her in the house and we spend on her from this money for medicine and food, how do we handle this assistance? How do we distinguish our money from her money? I ask for a detailed and clear answer.

The Shaykh : Yes. He says: Regarding this mentally disabled daughter, it is obligatory for her mother to have custody of her and care for her, because she is a trust. It is not permissible to take a wage for this custody, because this custody is a religious obligation, and religious obligations are not compensated with a wage, because her reward with Allah is greater than this world and what is in it. So let her seek reward and fulfill the duty of custody. However, if she is unable to do so and another woman is brought in to serve her, then the other woman is taken from these riyals that come from the government. As for taking these riyals...
If the father is the one who takes it, he has the right to do so, based on the hadith: "You and your wealth belong to your father."
As for the mother, she does not take. But she spends on her from these riyals in a good manner. And she does not take more than what this mentally disabled woman needs from the riyals. Yes.

The questioner : Food. She asks, "Shaykh, what do we do about her food?"

The Shaykh : Her food is taken from her riyals in the amount she eats. If, for example, there are five people in the house and this woman is the fifth, what is her share of the maintenance? One-fifth. She is responsible for one-tenth, and so on.
