What must a couple do to atone for an abortion that occurred 19 years ago, in the early stages of pregnancy and without confirmation, and with their consent for reasons they now consider flimsy?

If the miscarriage did not show the formation of a human being, then what is obligatory is repentance to Allah Almighty, and neither blood money (diyah) nor expiation (kaffarah) is obligatory, according to the majority of scholars. Some scholars, however, went further, stating that blood money and expiation are obligatory as a precautionary measure if 40 days had passed for the fetus. If there is doubt about the passing of 40 days, the default assumption is that they have not passed.
