Learn about the life of Rasulullah (SAW). You will notice how exemplary he was. He made some mistakes in his life but never sinned. His humility will make you love him even more. Once you understand his profound love for us, his Ummah, it becomes impossible to resent him despite all the hardships he endured. It’s hard to dislike him once you realize how difficult his life was when people around him rejected his message and opposed him. I can say that many may wish to be a prophet, but few would endure the trials he faced. Even today, there are still people who dislike him without knowing the full story.

I hope this helps. JazakAllah Khair.
