Keep your promises and commitments even after someone has died; Honor your loved ones by fulfilling their wishes; Do good deeds for deceased family members; Respect those who have passed away by remembering them positively through your actions.

In this hadith, the Prophet Muhammad is advising Sa'd to fulfill an outstanding vow that his mother had made before she passed away. This shows us the importance of fulfilling our promises and commitments even after someone has died. It also teaches us to honor our loved ones by fulfilling their wishes and promises even if they are no longer with us in this world. We should remember them in a positive way by doing good deeds for them and honoring their memory through our actions.
