Respect your loved ones even when they are no longer with you; Do good deeds; Be generous towards others; Follow Allah's commands.

This hadith speaks to the deep love that the Prophet Muhammad had for his first wife, Khadija. It is said that even after she passed away three years before he married 'A'isha, he still spoke fondly of her and was commanded by Allah to give her glad tidings of a palace of jewels in Paradise. This shows us how much respect and admiration he held for her even after she was gone, which serves as an example to us all on how we should treat our loved ones even when they are no longer with us. Additionally, it also teaches us about the rewards that await those who do good deeds in this life; as it is said that whenever the Prophet slaughtered a sheep he presented its meat to Khadija's female companions.
