Pray for your deceased brother's forgiveness and mercy from Allah. Be kind and forgiving towards others while they are alive as well.

The Prophet Muhammad (PBUH) taught us a valuable lesson about praying for the forgiveness of our deceased brothers. He gave this lesson when he heard about the death of An-Najashi, the ruler of Ethiopia. He said that we should pray for his forgiveness and mercy from Allah. This hadith teaches us that even if someone has passed away, we can still ask Allah to forgive them and show them mercy in their afterlife. We should also remember that it is important to be kind and forgiving towards others while they are alive as well, so that we can ensure their place in paradise after they have passed away.
