What is the ruling on supplicating against oneself that God take from the supplicant's lifespan and add to his sick mother's lifespan, and will God punish for this supplication?

It is prescribed to supplicate for the mother's healing and well-being. It is impermissible to supplicate evil upon oneself, and the remedy for this is repentance, seeking forgiveness, and righteous deeds. As for asking Allah to increase the mother's lifespan from the supplicant's own lifespan, there is no known text that deems it a sin; rather, it appears permissible, due to the story of Adam and David, where Allah increased David's lifespan from Adam's.
