THE SUN ROTATES

In 1609, the German scientist Yohannus Keppler published the ‘Astronomia Nova’. In this he concluded that not only do the planets move in elliptical orbits around the sun, they also rotate upon their axes at irregular speeds. With this knowledge it became possible for European scientists to explain correctly many of the mechanisms of the solar system including the sequence of night and day.

After these discoveries, it was thought that the Sun was stationary and did not rotate about its axis like the Earth. I remember having studied this fallacy from Geography books during my school days. Consider the following Qur’anic verse: “It is He Who created The Night and the Day, And the sun and the moon: All (the celestial bodies) Swim along, each in its Rounded course.” [Al-Qur’an 21:33]

The Arabic word used in the above verse is yasbahûn . The word yasbahûn is derived from the word sabaha. It carries with it the idea of motion that comes from any moving body. If you use the word for a man on the ground, it would not mean that he is rolling but would mean he is walking or running. If you use the word for a man in water it would not mean that he is floating but would mean that he is swimming.

Similarly, if you use the word yasbah for a celestial body such as the sun it would not mean that it is only flying through space but would mean that it is also rotating as it goes through space. Most of the school textbooks have incorporated the fact that the sun rotates about its axis. The rotation of the sun about its own axis can be proved with the help of an equipment that projects the image of the sun on the table top so that one can examine the image of the sun without being blinded. It is noticed that the sun has spots which complete a circular motion once every 25 days i.e. the sun takes approximately 25 days to rotate around its axis.

In fact, the sun travels through space at roughly 150 miles per second, and takes about 200 million years to complete one revolution around the center of our Milky Way Galaxy.

“It is not permitted To the Sun to catch up The Moon, nor can The Night outstrip the Day: Each (just) swims along In (its own) orbit (According to Law).” [Al-Qur’an 36:40]

This verse mentions an essential fact discovered by modern astronomy, i.e. the existence of the individual orbits of the Sun and the Moon, and their journey through space with their own motion. The ‘fixed place’ towards, which the sun travels, carrying with it the solar system, has been located exactly by modern astronomy. It has been given a name, the Solar Apex. The solar system is indeed moving in space towards a point situated in the constellation of Hercules (alpha Layer) whose exact location is firmly established.

The moon rotates around its axis in the same duration that it takes to revolve around the earth. It takes approximately 29½ days to complete one rotation. One cannot help but be amazed at the scientific accuracy of the Qur’anic verses. Should we not ponder over the question: “What was the source of knowledge contained in the Qur’an?”
