What is required of a mother if her daughter drowns without any negligence on her part?

The first message received was from the questioner, Latifah bint 'Abdullah ibn Shu'lan, who says in her message: The mother went out in the past to a place with grass to gather it for her livestock and cattle, and she left her small daughter with her mother. The daughter was one year old, and she slipped away from her grandmother and went to a pool of water, where she fell in and died. The mother’s brother, who had gone to the pool, lifted the girl and found her dead. This mother is asking about her ruling, and she is now old and weak, so what should she do? Please advise us on this.
Answer: In the name of Allah, the Most Gracious, the Most Merciful. Praise be to Allah, and may Allah send blessings and peace upon the Messenger of Allah, upon his family and his Companions, and upon those who follow his guidance.
As for what follows: There is no blame on the mother in this incident; because she did not act negligently as long as she left her with her mother, and small boys and girls generally cannot be kept under control. So the fact that she went to the pool and fell in is something that cannot be controlled, and there is no blame in that. She owes no blood money and no expiation. Yes.
The presenter: May Allah reward you.
