Is unintentional killing expiation obligatory for a mother whose three-year-old daughter died—after falling into a pot of hot water the mother had prepared for washing clothes—as a result of her negligence and inattentiveness towards her?

The mother must pay expiation (kaffarah) for accidental killing and blood money (diyah) if she was negligent in safeguarding her daughter. The expiation is: freeing a believing slave; if she cannot find one, then fasting for two consecutive months. The blood money is to be paid to the heirs of the child unless they forgive it.
