Let others say and prejudice you, what is important before God you are always right and in accordance with His rules.
Defamation is indeed very easy, especially if the slander comes from the ears and verbal that is not clear, because the more unclear it will be more cruel in reality.
So are you sad about what you experienced? do not! because those who should be sad are those who cannot keep their mouths and ears.
And believe that God always sees you fairly, even very justly for what you do, so you don't need to care about the bad judgment of humans who seem to judge you cruelly.
Let you be bad in the eyes of other human beings, let you become a material for gossip from oral to verbal, provided that in the eyes of Allah you always do according to His rules.
Let you be looked at by one eye by humans, provided that Allah always sees you perfectly, and provided you never violate the path that God has given.
It's up to people to talk about you badly at all times, as long as what you do is never as they say.
Let you be insulted, considered bad, considered inappropriate, and slandered with something very cruel, as long as you remain patient and realize that Allah will always be on your side.
Truly Allah sided with anyone who is on His path, then if you believe you have rightly according to Him then you need not feel disturbed by human words.
So there's no need for you to be sad because human speech is irresponsible, you don't need to feel frail and like that, just enough you know that God never turns a blind eye to the truth.
God is always fair in judging every act of his servant, then if you are right and someone else is guilty, then they will get a reward from each of him.
So always remember wisely when there are people who know your life, that the most important thing is God's judgment, not human beings who can only be prejudiced and judgmental.
Yes, You remain calm in patience, let others say bad to you according to his mind, and what matters is not with you.
