Ruling 1681

After a father’s death, the eldest son must, based on obligatory precaution, keep his father’s qaḍāʾ fasts of the month of Ramadan as per the details mentioned in Ruling 1370 concerning prayer. Instead of fasting each day, he can give 750 grams of food to a poor person even from the deceased’s property if the heirs consent to it.
