Speak kindly about others , Be forgiving , Show respect

This hadith is about respecting both the dead and living. It was narrated by Ibn 'Abbad that a man slandered one of his forefathers from the time of Jahiliyyah, which is a period before Islam. Al-'Abbas slapped him in response to this slanderous act. His people then wanted to retaliate but news of this reached Prophet Muhammad (PBUH). He then ascended the Minbar and asked who they thought was most noble before Allah? They replied that it was him. He then said that Al-'Abbas belonged to him and he belonged to Al-'Abbas; thus warning them not to defame their dead or offend their living. Those people came back asking for forgiveness from his anger so he prayed for them instead. This hadith teaches us that we should respect both our dead ancestors as well as our living family members by not speaking ill of either one of them or engaging in any kind of offensive behavior towards them. We should also be forgiving when someone wrongs us instead of retaliating with violence or harsh words as Prophet Muhammad did in this situation by praying for those people instead of getting angry at them.
