This is not how science suggest the solar system came to be nor how the earth formed. the hot dense "smoke" at the centre of the solar system heated up and this mechanism formed the sun in which was born with quite a large bang, this foce pushed the lighter elements gas or "smoke" as you call it outwards while the heavier more dense material remained closer hence why outer planets are gas bags and inner are rocky. After the formation of the sun, the planets of our solar system started to form and for earth this period is known as "the great bombardment", many more planets existed in our early solar system all known as proto planets, planets in early formation. two young protoplanets collided (one was called earth). the two planets collided at this early stage combinging mass and the moon was formed. heavy elements like Iron were too dense to escape the proto planet and this is why the moon has no iron.
Some of those hadith are also talking about the human perspective of things. I hope to ask someone knowledgable about this subject. There is a page about this at

The gas at the start of the universe is the subatomic 'zoo' of radiation. The early universe was full of thick 'fog'. I was not claiming that gasses caused the big bang.
You did not mention how atmospheres form in this passage, you just talked about where the smoke came from, and some other stuff. Also, the centres of the gas planets (below the seas of metalic gas) are made of solid rock and metal. Jupiter's core is the size of the Earth. Such large gas layers were kept away from the inner planets by the the solar wind.
I did not include most of the information you talked about here because it is not really needed. But, if you insist, I will write a better version:
1. The sun pushes lighter elements out from the centre, leaving the heavier ones in the middle. An acretion disk forms around the sun.
2. The heavier elements accrete into rocky dust.
3. The rocky dust acretes into larger bodies, such as planetoids.
4. The Earth reaches a size large enough to hold an atmosphere.
5.The Earth's atmosphere begins to accumulate.
6 The atmosphere reaches the largest size allowed by the then furious solar wind, and gas in the inner solar system is used up.
See, six periods. You could say the first four were when the Earth was formed, and the last two were when the 'heavens' (which were gas, or smoke) and the Earth were coming together.
