Whats real is always whats happening behind, whats fake is usually whats happening in front. Action do speaks louder than words. And words spoken always leave longer lasting scar. Its true that we should react of what happened in front, whilst behind our back, Allah is our protector, our best defender if we are maltreated.
Let them judge based on one side of the story as they see fit, and closed their ears from another, even if they know just a part of. After all, those who knows about it all did have a different take upon it.
Allah is the best judge. Let Allah take care of the repayment. Because Allah knows all that had been transpired throughout, spoken, done, of forgiveness asked and of the pain that felt.
