In Islam, dreams involving fighting can hold various meanings, depending on the context of the dream and how the dreamer felt during the experience. Here are a few points to consider based on Islamic teachings:

1. Symbol of Inner Conflict: The dream about fighting might symbolize an internal struggle or conflict you are experiencing. It could reflect the battle between your desires and your spiritual obligations. In the Qur'an, such an internal conflict is often related to the concept of Jihad al-Nafs, or the struggle against one's own soul and desires.

2. Peace Amidst Fear: Feeling peaceful despite the frightening nature of the dream suggests a sense of resolution or understanding within you about the conflict. It may indicate that while challenges are present, you have the inner strength to overcome them, trusting in Allah (سبحان الله).

3. Spiritual Reflection: This dream encourages self-reflection about the challenges you are facing and reminds you to turn to Allah for guidance. The peace you felt may be a sign of reassurance from Allah that, despite difficulties, He is with you.

4. Hadith Guidance: According to the Prophet Muhammad (ﷺ), dreams that distress us may come from the influence of Shaytan, whereas those that bring peace may be from Allah. It is advisable to seek refuge in Allah from any unsettling elements within the dream and to focus on the peaceful aspect that may have been divinely inspired.

It may serve as a reminder about the importance of patience, perseverance, and reliance on Allah during trying times. Consider offering additional prayers and asking Allah for clarity and peace in your life.
