why should we avoid hating others?

Assalam u alayekum!
May peace be upon you!

Sufi's always teach to love others because all of us have a common relation.what?????
We all are the creation of One Lord.The Lord of the heavens and the earths and the things within.

From psychology's point of view,hatred is a very bad thing.We should avoid it.Because when we hate someone,we are actuallt thinking about his bad traits.We are neglecting his bad traits and making him stand in the accused box and we consider ourselves as judge.We try to declare him guilty forcefully.Thinking him over and over ,actually makes our sub-conscious to react like that person.That is why we should avoid hating others.

Love is the extract of our religions.Jesus May peace be upon Him taught that love others.Seal of Prophets Our beloved Muhammad May peace and blessings of Allah be upon Him forgave people throughout His life.Once during preaching in Taayif,people stoned him so much that His Holy shoes were full of blood.The Angel Gabriel came to Him and asked Him to curse them.But He refused an rather He prayed in their favour.It was the result of that Blessed prayer and that most beautiful attitude that people of Taayif later became Muslims.

Hatred repels hearts.Love brings them closer.Good intentions,positive thinking and trust in the Lord of Heavens and Earths and His absoutely Supreme authority makes us work better.

May the Lord of Heavens and Earths make us among thos who love Him and His creations.aamin
