The word "وريحان" (rayhan) in Arabic indeed commonly refers to the herb basil. However, in many contexts, especially in religious or spiritual texts, it can take on a metaphorical meaning. In such contexts, "rayhan" is used to represent bliss, contentment, or any pleasant and fragrant experience, akin to the refreshing nature of basil. In Islamic tradition, "روح و ريحان" (rooh wa rayhan) is a phrase that signifies comfort, peace, and spiritual bliss. It's often used in a figurative sense to describe the blessings and tranquility of paradise. So, while "rayhan" literally means basil, its usage in supplications or religious texts is usually symbolic, relating to the broader connotations of comfort and heavenly bliss rather than the literal herb.
