In old times, people observed certain objects appearing suddenly in the sky and behaving differently from planets. From their appearance they gave them the Greek name "Komet" meaning "hairy one, hair of the head". And today we call them "Comet", an astronomical object with long tail.

Man knows about "comets" for the last 2500 years and has observed and recorded about 2000 comets. At the time of revelation of Qur’ān, the appearance of large comets was regarded as atmospheric phenomenon and same was the perception of Aristotle. It was not regarded as celestial bodies:

"Appearances of large comets were regarded as atmospheric phenomena until 1577, when Danish astronomer Tycho Brahe proved that they were celestial bodies. In the 17th century British scientist Isaac Newton demonstrated that the movements of comets are subject to the same laws that control the planets in their orbits.

Grand Qur’ān had clarified their misconception 1400 years back that it were celestial bodies like the planets.

  • It is a fact that Our Majesty have adorned the Sky of the Lowly World-Earth with the attraction-beauty of the Planets. [37:06]

    Planets

  •  And Our Majesty have made her (the Sky of the Earth) secure from every Cursed and condemned shai'taan/satan— [37:07]

  • They cannot make themselves to fully listen the talk of Assembly of Exalted Chiefs —

  • And they are hurled/darted from every side — [37:08]

  • In the manner/for driving/expelling/banishing/pushing them away with violence [not to kill but to make them run away]—

  • -- Know it, a perpetual torment is prepared - in wait for them --. [37:09]

  • Except regard to safety the one who clandestinely picked a cut piece of the talk —

  • Thereupon, a piercing, shone and intensely glistened fire ball [Comet-read with 67:05] followed him  [37:10]

Another celestial body which is used for beautification and protection of the Sky of the Earthly world is:

  • And Our Majesty have adorned the lowest Sky of Lowly World-Earth with Comets, and have rendered it protected—[Reder 41:12]

  • And Our Majesty have indeed decorated the lowest Sky of Earth with Comets—

  • And We have rendered them (comets) a source of stone-hurling for the Shai'teen [Evil Ones -Satans amongst species Jinn who rise in upper atmosphere to listen something]

  • And Our Majesty have prepared for them (Satans) the punishment of the scorching heat - Hell-Prison. [67:05]

The Arabic word: is much more reflective with great precision to describe the object than the word "komet" assigned by the Greeks. It becomes visible only when it reaches near the Sun.

This word stems from Root: ص ب ح means day break; it is the time when day becomes eminent and visible. It conveys the perception and meaning of the point of beginning. It reflects a visible position. And therefore it is used to call someone as beautiful, pretty or elegant peculiarly in the face, bright in the face. مُصبِج is the one who enters at the time of morning. اصبَجَ means hairy one with whiteness naturally intermixed in it with redness, shining hair.

The peculiar information about Comets is that His Majesty has rendered them: stemming from Root: ر ج م which signifies the throwing, or casting, of stones. Today we know about Meteoroid: A small rocky or metal object, usually between the size of a grain of sand or a boulder, that orbits the sun; and Meteor: A meteoroid that enters the earth’s atmosphere and vaporizes. Also called a “shooting star.”. It originates from a comet or asteroid. And we know Meteor shower: A collection of meteors visible when earth passes through a trail of debris left by a comet.
