The Noble Qur’an says;

“…and do not backbite one another. Does one of you like that he eats the flesh of his dead brother? You would abhor it…” (49:12)

Once a Sahabi (companion) asked the Holy Prophet ﷺ, “O Prophet of Allah! If I am doing Gheebat about someone but what I am saying is true, is it still a sin?” The Holy Prophet ﷺ replied, “If what you are saying bad about a person is true and you are telling the truth, then it is Gheebat. But if what you are saying about him is not true and you are telling a lie, then you are also committing the sin of Bohtaan in addition to Gheebat.”

In a Hadith, the Holy Prophet ﷺ has told us a remedy that can only come from a Messenger of Allah. If we follow this advice it would lead to peace and harmony in our society and abolition of all conflicts. That remedy is 

احب لا خیک ما تحب لنفسک

واکرہ لغیرک ما یکرہ لنفسک

It means that “like for your brother what you like for yourself, and dislike for your brother what you dislike for yourself.”
