Miracle: Calculating the Speed of Light from the Qur’an

Posted on April 4, 2010


Based on the work by Egyptian Physicist, Mansour Hassab El Naby.

The greatest speed C, denoting the velocity of light in vacuum, is hinted at in two glorious Qur’anic verses relating this fundamental universal constant C with the motion of the Earth-Moon system. A new relativistic interpretation of this Qur’anic relation gives C=299792.5 km/s in an extremely marvelous agreement with the accepted international value. This astonishing result emphasizes the unity of the physical world, the validity of the special theory of relativity and the authenticity of the Glorious Qur’an for unbelievers.

A rebuttal to some who would challenge the above verse.

On Youtube, some people of other faith-based communities have challenged the above video by referring to Sura 70, verse 4, and state that the above video is a Muslim deception. As usual, these detractors of the Qur’an only refer to the English translation of Yusuf Ali, and cite out of context.

There is no deception because the Qur’an–being God’s Word–never contradicts itself. The two ayahs describe different phenomena and days at two different points in time. Please read the verses (including the whole chapter/Sura they come from) carefully in their original Arabic, instead of relying on excerpted English translations. The first verse, Surah 32, verse 5 describes the current/normal state of affairs in the present. The second verse describes the Day of resurrection in the future. Here is the best existing translation of the meaning of the second verse (Sura 70: verse 4) by Sheikh Ahmad Zaki Hammad:

The Angels, and Gabriel, the Spirit, Ascend to Him in a Day–wherein Humanity shall be resurrected–the measure of which is fifty thousand years.”

The reason the second day is different in length is because it refers to the Day of the Resurrection as indicated by the very title of the Sura (chapter), and the description of the end of the world that follows.

The detractors of Islam also contend that light is always a constant. However, when looking at as recently as two billion years ago, there are a number of physicists who contend that the speed of light may not always have been a constant. It may be constant currently, but who knows what will happen in another 2 billion years, or whenever the Day of Judgment occurs–as described in Surah 70, verse 4? Science is catching up with the Qur’an, not the other way around.
