PHASE 6: The formation of solar system or star system as smallest unit of galaxy. It begins as the surface of the planet gets colds and it becomes solid, accompanied with the stars which begin to shine.
“Which has created seven layers of skies (thibaaqaan)” (67:13)
Thibaaqaan is derived from the word thabiqa for thabiqa wa athbaqal baaba: aqfalahu : to cover, to close. Thabbaqasy syaiu: ‘amma: evenly. Ath thabaqaru: assaaffatu: layer.In the previous phases, the materials that compose the planets, stars and sun are the same that is hydrogen ball. But because their tiny mass, the hydrogen undergoes a very rapid reaction, and it change into iron. So, it’s understandable that the hydrogen reaction into iron in the proto planet goes much faster than the proto star. The fusion reaction of the hydrogen into the heavier substances makes the proto planet get colder. By the time iron produced, there are other compounds produced as a result of that reaction. Because the outmost layer (surface) is much colder than in the centre, the compounds later will form rocks. Actually, the planets also shine, not as bright as star of course, if it’s surface on the outermost part which consist of rocks and soil are omitted.
