Show kindness to your mother, sister, brother and the slave whom you set free.

This hadith is about showing kindness to those who are close to us. The Prophet Muhammad ﷺ taught that we should show kindness not only to our family members such as our mother, sister and brother but also those who are related by ties of relationship such as a freed slave or someone who is due binding on us. This hadith teaches us that we should be kind and generous towards all people regardless of their social status or position in life. It also reminds us that we have an obligation towards those who are related by ties of relationship and it is important for us to fulfill this obligation with kindness and generosity.
