The Expiation of One Who Placed a Cup and a Child Drank from It

Question:
May Allah conceal the fault of the woman who says: A woman placed a cup, and her child came and drank from the cup. Then, is there anything required of her? Since some people issued a ruling that she should fast for two consecutive months, or feed sixty poor people, is this correct?

Answer:
If she placed the cup within the child's reach, close to him where his hand could get it, and did not move it away from him, then she was negligent. However, if she placed the cup in a place that was not within the child's reach, but the child went to it and took it, then she owes nothing, because she was not negligent. This varies depending on her action. If she placed the cup near the child and within his reach, she was negligent and the expiation is required of her. But if she placed the cup in a distant place, not within the child's reach, and it was he who went to it and took it, then she owes nothing because she was not negligent.
