A rainbow is formed when sunlight is refracted, or bent, as it passes through raindrops in the atmosphere. The sunlight is then reflected inside the raindrop and refracted again as it exits, creating the spectrum of colors we see in a rainbow. Therefore, we can have a rainbow without using a firmament mirror prism by simply having sunlight, raindrops, and the right angle of observation. This natural phenomenon does not require any artificial or man-made devices to occur. **

Ultimately, it is up to the individual to seek guidance from religious scholars and make a decision based on their own understanding of Islamic principles. **
