Take care of your family while they are still alive; Remember your loved ones with fondness and joy rather than sadness and despair; Moderate your grieving process for those who have passed away.

This hadith teaches us that when a person passes away, their family's grief and sorrow can cause them to be tormented in the afterlife. It is important to remember that although it is natural to grieve for a loved one who has passed away, we should not let our grief become too overwhelming as it can have an effect on them even after death. We should strive to remember our loved ones with fondness and joy rather than sadness and despair. Additionally, this hadith serves as a reminder for us to take care of our families while they are still alive so that we do not regret anything when they pass away.
