Allah says: And [even] if We opened to them a gate from the heaven and they continued therein to ascend. They would say, ‘Our eyes have only been dazzled. Rather, we are a people affected by magic!’ (15:14-15)
This similitude is amazing since it presents a universal fact which humans previously were ignorant of, and only discovered during the age of space exploration in the sixties. The entire universe is engulfed in darkness. Light visible on earth is observed for two hundred kilometers, beyond that, darkness is to be witnessed in every direction, due to the rarity of water vapor and dust particles. Far removed is Allah from every imperfection. It is He Who informed us of this reality.
