Muslims should deal with illness and suffering through the following approaches:

1. **Faith and Patience (Sabr):** Maintain faith in Allah’s wisdom and be patient, recognizing that suffering can be a test or a means of spiritual growth.

2. **Dua (Supplication):** Regularly make supplications for healing and relief, asking Allah for comfort and strength during difficult times.

3. **Seeking Medical Treatment:** Pursue appropriate medical care and treatments, as seeking healing is encouraged in Islam, reflecting the belief that health is a blessing.

4. **Community Support:** Seek support from family and friends, and engage with the community for emotional and spiritual encouragement.

5. **Gratitude:** Practice gratitude for the blessings still present, focusing on positive aspects of life even amid hardship.

These approaches help Muslims navigate illness and suffering while maintaining spiritual and emotional resilience.
