The umbilical cord of a baby inflamed and caused its death after being cut

Q: A woman who gave birth to a female child cut the child's umbilical cord with a blade, and then tied it following the custom of other Bedouins. Two days later, the woman took the child to the hospital to be told by the doctor that the umbilical cord was infected with cancer as spoiled blood had accumulated causing the umbilical cord to be poisoned, and consequently causing the death of the child. Please bear in mind that the woman did the same with all children to whom she gave birth. Moreover, she did the same to another female child to whom she gave birth after the child mentioned above, and nothing bad happened. Is such a woman liable to a Kaffarah (expiation)? (Part No. 21; Page No. 386

A: If the reality is as you have mentioned, the woman is neither sinful nor liable to Kaffarah (expiation) regarding the death of her daughter. In fact, cutting the umbilical cord is the custom of all women and hence may not be the cause of the child's death. Actually, one is basically free from accountability unless otherwise proved.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
