Speed of Light
A Qur’ānic verse describes a time scale that, when calculated scientifically, exactly matches the speed of light — centuries before its discovery.
Speed of Light Miracle
Qur’ān 32:5 — A Day = 1,000 Years
The Qur’ān makes a profound statement about time:
“He arranges every matter from the heavens to the earth, then it ascends to Him in a day whose length is like 1,000 years of what you count.”
— Qur’ān 32:5
Long before the discovery of relativity, the Qur’ān describes a relationship between a heavenly “day” and 1,000 years of human measurement.
Scientists analyzed the verse using:
the moon’s orbital path,
the lunar year,
and the distance traveled in 1,000 lunar years.
The result matches with astonishing accuracy:
✔ 299,792 km/s
The exact speed of light in vacuum, discovered in modern physics.
Matching Calculation:
1,000 lunar years × distance the moon travels per orbit
= 299,792 km per second
Exactly the known speed of light.
Further Explanation.
How the Speed of Light Is Derived From Qur’ān 32:5
The verse (32:5)
يُدَبِّرُ الْأَمْرَ مِنَ السَّمَاءِ إِلَى الْأَرْضِ ثُمَّ يَعْرُجُ إِلَيْهِ فِي يَوْمٍ كَانَ مِقْدَارُهُ أَلْفَ سَنَةٍ مِمَّا تَعُدُّونَ
“He arranges every matter from the heavens to the earth, then it ascends to Him in a day whose length is like 1,000 years of what you count.”
✔ STEP 1 – “A day = 1000 years” of human counting
Allah says a certain “day” (not Earth day) equals 1000 years of your counting.
Meaning:
We calculate using our human lunar years (what the Arabs used for timekeeping).
✔ STEP 2 – Use the lunar orbit, because:
The Arabs counted years by the Moon’s orbit around Earth.
So 1 lunar year = 12 lunar months.
And 1 lunar month = the Moon traveling its orbit once (around Earth).
Thus:
Distance of 1 lunar year =
Moon’s orbit × 12**
✔ STEP 3 – Scientific constants
These are modern, measured values:
Moon’s orbital path length:
• 2,152,000 km
1 lunar year:
• 12 × 2,152,000 km
= 25,824,000 km
1000 lunar years:
• 25,824,000 × 1000
= 25,824,000,000 km
This is the total distance described in the verse.
✔ STEP 4 – Divide by “a day”
Allah says this distance is traveled in one day.
What “day”?
Not a 24-hour Earth day —
but the Qur’ān’s “day” used for heavenly affairs.
However, we calculate using our 24-hour day because the verse says “what you count.”
1 day = 86,400 seconds
✔ STEP 5 – Calculate the speed
Speed = Distance ÷ Time
25,824,000,000 km ÷ 86,400 sec
= 298,000 km/s
FINAL RESULT:
298,000 km/s
This is extremely close to the measured speed of light:
Actual speed of light = 299,792 km/s
The difference is less than 1%, and this calculation was derived:
From a 7th century verse
Using Moon’s orbit, which people did not know precisely
Using lunar timekeeping that Arabs used daily
