Surah Al-Jinn 72:8

وَأَنَّا لَمَسْنَا السَّمَاءَ فَوَجَدْنَاهَا مُلِئَتْ حَرَسًا شَدِيدًا وَشُهُبًا

72:8 Lamas-nâلَمَسْنَا is from lamasaلَمَسmeaning to seek something without obtaining it or unable to touch it, whereas massa éo¿ is something that can be obtained and felt with the senses of touch. Muli’atمُلِئَتْ from malâ’ملاء signifies fullness, something that fills with awe and attraction. The chiefs are called malâ’unملاءٌ as they fill the eyes of ordinary people with awe and attraction. Harasaحَرَسًا means to guard strongly. Shadîdشَدِيدًا is something that is tightly bound (like the power of gravitation), something violent, severe, strong, terrible and stern. The word is derived from shadda - to bind tightly, strap firmly, hard and strongly. Shahâbشُهُابً is a comet, a small body that orbits the sun and, when close enough to the sun, exhibits a visible coma or a tail from the effects of solar radiation upon the comets nucleus. Comets have their own orbital periods, ranging from a few years to hundreds of thousands of years, while some are believed to pass through the inner solar system only once before being thrown out into interstellar space. Short-period comets are thought to originate near the orbit of Neptune and long-period comets are believed to originate at a much greater distance from the sun, in a cloud consisting of debris left over from the condensation of the solar nebula. If the comets path crosses earth’s path, then there are meteor showers as the earth passes through the trail of debris. The comet-like bodies in the outer solar system may number millions. The number of naked-eye comets averages roughly one per year. When a historically bright or notable naked-eye comet is witnessed by many people, it may be termed a Great Comet. The expression used in this verse and the following refer to the quest of getting knowledge on some cosmic observations and laws.
