Perform your religious duties and fulfill your commitments even after death if you are unable to do so yourself .

This hadith is about fulfilling the obligations of Hajj and fasting in fulfillment of a vow on behalf of someone who has passed away. The Prophet Muhammad ﷺ was asked by Abu Ghawth bin Husain, a man from Furu’, about his father's obligation to perform Hajj before he died. The Prophet ﷺ advised him to perform it on behalf of his father as well as any other fasting in fulfillment of a vow that he may have owed. This hadith teaches us that we should fulfill our obligations even after death, whether it is an obligation to God or an obligation to another person. It also teaches us the importance of honoring our parents even after they have passed away by fulfilling their religious duties if they were unable to do so themselves.
