لم تكن ... فقط ... بل ...
This pattern is used to contrast two ideas and mean "not only ... but also ...". You can reuse it when you want to say that something has a deeper or broader meaning than one simple purpose. Example: "الرحلة لم تكن فقط عن الوصول بل عن الاستمتاع بالطريق." = "The trip was not only about arriving, but also about enjoying the journey.".
الرحلة لم تكن فقط عن الوصول بل عن الاستمتاع بالطريق.
The trip was not only about arriving, but also about enjoying the journey.
