A woman with two children; the older one rolled over the younger while sleeping, and the younger died

Question:
The questioner, Umm Hanifah, in her final question, says: A woman has two children, and while they were sleeping, the older sister rolled over the younger one, and she died. What is obligatory for this woman? If it is fasting, is there an alternative?

Answer:
The mother owes nothing, because she did not neglect her duty in this matter. Rather, the expiation is upon the older one who rolled over the younger, if this older one has reached puberty. If she has reached the age of accountability, then it is obligatory for her to pay the expiation for an accidental killing, which is freeing a slave. If she does not find one, then she must fast two consecutive months. As for the mother, she owes nothing in that, because she is not the cause and did not do it directly. Yes.
