In the Name Of Allah, Most Beneficent , The Merciful

Prostration to God “Seest thou not that to GOD prostrates everyone in the heavens and the earth, and the sun, and the moon, and the stars, and the mountains, and the trees, and the animals, and many people? Many others among the people are committed to doom. Whomever GOD shames, none will honor him. Everything is in accordance with GOD's will.” The Holy Quran- 18 Surat Al Haj(the pilgrimage)

The stars and the trees prostrate(6) Arrahman To GOD prostrates everyone in the heavens and the earth, willingly or unwillingly, and so do their shadows in the mornings and the evenings. (15 Arrad-the thunder Cosmic Prayer Solar Eclipse The stars and the trees prostrate(6) Arrahman Lunar eclipse

“The star and the trees prostrate” (6- Arrahman) The Holy Quran

“By the Star as it collapse” 1(A Nnagim(the Star) The Holy Quran During most of a star's lifetime, nuclear fusion in the core generates electromagnetic radiation, including photons, the particles of light. This radiation exerts an outward pressure that exactly balances the inward pull of gravity caused by the star's mass. As the nuclear fuel is exhausted, the outward forces of radiation diminish, allowing the gravitation to compress the star inward. The contraction of the core causes its temperature to rise and allows remaining nuclear material to be used as fuel. The star is saved from further collapse -- but only for a while. Eventually, all possible nuclear fuel is used up and the core collapses. How far it collapses, into what kind of object, and at what rate, is determined by the star's final mass and the remaining outward pressure that the burnt-up nuclear residue (largely iron) can muster. If the star is sufficiently massive or compressible, it may collapse to a black hole. If it is less massive or made of stiffer material, its fate is different: it may become a white dwarf or a neutron star.

“By the Star as it collapse” 1(A Nnagim(the Star) The Holy Quran 1- Electromagnetic radiation pressure = Gravitation 2- Electromagnetic radiation pressure = 0 The Star collapses under its own gravitational forces and induces gravitational red shift

White Dwarf When small stars (up to 8 times the size of the Sun) exhaust their nuclear fuel, they typically shed large amounts of matter, leaving a core that eventually cools and contracts gravitationally to about the size of the Earth. The result is a white dwarf: the more massive it is, the greater its inward gravitational pull, and the smaller it becomes. A teaspoonful of white dwarf material would weigh five-and-a-half tons or more in the Earth's gravity! Yet a white dwarf can contract no further; its electrons resist further compression by exerting an outward pressure that counteracts gravity. There are many white dwarfs in our galaxy, but most are too dim to be seen. One of the first to be discovered was Sirius B, the dense companion star to Sirius. Ref ( cosmogony Course)

“And that He is the Lord of the Sirius” 49- Annagm(the star), The Holy Quran Sirius and its white dwarf companion Series B has collapsed and became a white dwarf. This is very likely to be the prostration of the star. Sirius B prostrating

The action of prostration The action of prostrations is literary the collapse of the body to the smallest possible volume. This is actually what happens to collapsing stars. Surat the star, starts with a swear of the collapsing star. In the same Surat, verse 49, “And that He is the Lord of the Sirius” While at the end of this surat ,an order is given “But fall ye down in prostration to God and worship”

*Have they not observed all things that Allah hath created, how their shadows incline to the right and to the left, making prostration unto Allah, and they are lowly ?(48) To GOD prostrates everything in the heavens and everything on earth - every creature - and so do the angels; without the least arrogance(49) The Holy Quran Surat ANnahl(the bees).

The Rock is Prostrating Praise be to My Lord Most High

And The Trees

“The star and the trees prostrate” (6- Arrahman) The Holy Quran Sirius B prostrating Praise be to My Lord Most High Sirius A The tree is kneeling, the shadows are prostrating

“Only those believe in Our revelations who, when they are reminded of them, fall down prostrate and hymn the praise of their Lord, and they are not proud (15) “ The Holy Quran Surat ASsgda

Nay, Obey not thou him. But prostrate thyself, and draw near (unto Allah). The Holy Qurn-19- Al Alaq
