Spiritual care is essential to the healthcare plans of critically ill patients and their families. However, spiritual care remains neglected and requires healthcare institutions and providers’ attention to be incorporated into healthcare management plans, especially for critically ill Muslim patients and their families. To date, no review has been conducted to discuss spiritual care in adult critical care Muslim patients. Spiritual care and Holy Quran recitation have been reported to be practical non-pharmacological interventions for critically ill Muslim patients. However, there is a need for Islamic healthcare institutions and providers to pay further attention to including spiritual care in the healthcare management plans of their patients. Also, future research is recommended to test the effectiveness of incorporating spiritual care in the healthcare plans of critical care patients.
