Is a mother subject to Qisas for intentionally killing her own child?

Primary text

The soundest position is that the mother is not subject to Qisas for killing her child, adhering to the Prophet's saying, 'A father shall not be killed for his son,' which applies analogously to the mother as one of the two parents. She is more deserving of being spared retribution due to her greater right to kindness. The established principle that waives Qisas for the father (the merit of parenthood) applies here, and the lack of legal authority (Waliyah) over the child is irrelevant, as evidenced by the waiver of Qisas for the father killing an adult child over whom he has no authority, and for the grandfather who also lacks such authority.
