The document discusses how the Quran contains references to the speed of light centuries before it was measured by scientists. [1] It describes Quranic verses that reference the moon's orbit and uses mathematical calculations based on the verses to determine the speed of light. [2] The calculations yield a value of 299792.5 km/sec, matching modern scientific measurements. [3] This suggests the Quran contains scientifically accurate information and supports its claim as a divine revelation.
