´It was narrated that ‘Ali said:` “The Messenger of Allah (ﷺ) said: ‘The miscarried fetus will plead with his Lord if his parents are admitted to Hell. It will be said: “O fetus who pleads with your Lord! Admit your parents to Paradise.” So he will drag them out with his umbilical cord until he admits them to Paradise.’”
