*Surah (13) Ra'ad, verse 2*
اللَّهُ الَّذِي رَفَعَ السَّمَاوَاتِ بِغَيْرِ عَمَدٍ تَرَوْنَهَا ثُمَّ اسْتَوَي عَلَي الْعَرْشِ وَسَخَّرَ الشَّمْسَ وَالْقَمَرَ كُلٌّ يَجْرِي لأَجَلٍ مُسَمّي يُدَبّـِرُ الأَمْرَ يُفَصّـِلُ الاَيَاتِ لَعَلَّكُم بِلِقَآءِ رَبّـِكُمْ تُوقِنُونَ
_"Allah is He Who raised the heavens without any pillars which you (can) see, then He established Himself on ‘Arsh (the Throne of authority) and subjected the sun and the moon, each one runs unto an appointed term."_
In Tafsir Al-Mizan, ‘Allamah Tabataba’i says that the purpose of the Qur’anic word / *tafsil* / (explanation) is separation of the celestial planets and the earth from each other. The observation of this separation makes us aware of the separation of people in the Hereafter.
The Arabic word /‘ *amad* / is the plural form of /‘ *amūd* / which means ‘ *pillar* ’. However, when we do not see something, it cannot be taken as a reason for its inexistence.
This verse unveils a scientific fact which was not manifest for anyone at the time of the revelation of the Qur’an. At that time the Ptolemaic system governed over the scientific centers and the thoughts of people. According to it, the planets and heavens were considered as the layers of an onion which were located over each other, and the earth was in the center.
About one thousand years after the revelation of these verses, the knowledge of humankind realized that the mentioned theory was utterly wrong and the reality is that the celestial planets each rotates on a fix axis in its own position, suspending and also invariable, without having anything to lean against.
The only factor which supports them to be fix in their own particular rotations is the equilibrium resulted from the attractive and repelling forces. This equilibrium of the attractive and repelling forces, as an unseen pillar, keeps the celestial planets fix in their positions and orbits.
But the material system of the world is not eternal, and all the celestial bodies, such as the sun and the moon, will continue to rotate along their defined orbits until an appointed time.
Next to that, the Qur’an implies that these acts of to and fro are not undue and do not exist with no result, because it is Allah Who arranges everything. Then there is an account for every movement, and every account has been appointed for a particular aim.
How can one say that the sun and the moon are not at the service of man while they illuminate and warm the scene of his life by their lights? Without sunshine, there will be no movement and development on the earth.
There is a very attractive tradition in this field narrated from Amir-ul-Mu’mineen Ali (as) who has said:
_“These stars, which are in the sky, are some cities like the cities on the earth, every one of which is connected with another by means of a pillar of light.”_
