Taken from the verse An Nur: 35, which often referred as the Light verse, Misykat is from the word of ‘kamisykatin’.
I put the explanation about this verse from this site http://www.islamicstudies.info/tafheem.php?sura=24&verse=35&to=36, which i think is clear enough for common people to comprehend.
“In this parable, Allah has been likened to the Lamp and the universe to the Niche. The glass shade is the veil behind which Allah has concealed Himself from His creation. This veil is not a physical veil for concealment, but a veil caused by the intensity of divine manifestation. The human eye is unable to see Him not because of the intervening darkness but because of the intensity of the all pervading, all-embracing Light radiating through the transparent veil. The human vision which is limited in nature cannot comprehend it. It can only comprehend and perceive limited physical lights which vary in brightness, which disappear and reappear, and Which can be perceived only by contrast to existing darkness. But the Absolute Light has no confronting darkness. It does not vanish, it shines forth and pervades all around with everexisting glory; it is beyond human perception and comprehension.
As for the lamp which is lit with the oil of a blessed olive tree, which is neither eastern nor western, this is a metaphor to give an idea of the perfect light of the lamp and its brilliance. In antiquity the source for brilliant light were the olive lamps, and the most superior oil for the purpose was that obtained from a tree standing in an open and elevated place. The epithet of Lamp for Allah in the parable does trot mean that Allah is deriving His energy from some external source. It only means that the Lamp of the parable is not an ordinary lamp but the most brilliant lamp that can be imagined. Just as a brilliant lamp illuminates the whole house, so has Allah illuminated the whole universe.
Again, the words “its oil is (so fine) as if it were going to shine forth by itself though no fire touched it”, are also meant to emphasize the brilliance of the light of the lamp, which is being fed by the finest and most readily combustible oil. The olive and its being neither eastern nor western, and high combustibility of its oil by itself’ (without fire), are not the essential elements of the parable, but attributes of the lamp, which is the primary element of the parable. The essential elements of the parable are only three: the Lamp, the Niche and the transparent Glass Shade.
The sentence: His light may be likened, dispels the possible misunderstanding that one could have from the words: Allah is the light of the heavens and the earth. This shows that the use of the word light for Allah does not at all mean that the essence of His Being is nothing but light. In essence, He is a Perfect Being, Who is All-Knowing, All- Powerful, All-Wise etc. and also possessing all Light has been called Light itself because of His Perfection as a source of Light, just as somebody may be called Grace on account of his being highly gracious and beneficent and Beauty because of his being highly beautiful and attractive.
That is, although Allah’s Light is illuminating the whole world, everybody does not and cannot perceive it. It is Allah alone Who blesses whomsoever He wills with the capacity for perceiving His Light and benefiting by it. Just as the day and night are alike to a blind man, so is the case of a man without the gift of inner perception. He may see the electric light, the sunlight, the moonlight and the light from stars, but he cannot perceive the Light of Allah. For him there is nothing but darkness in the universe. Just as a blind man cannot see the stone in his way unless he stumbles over it, so is the man without the gift of inner perception, who cannot perceive even those realities around him which may he all brilliance and shining by Allah’s Light. He will perceive them only when he is overtaken by the consequences of his own misdeeds.
This means two things: First, He knows what parable can best explain a certain reality, and secondly, He knows who is entitled to receive this bounty and who is not. Allah has no need to show His Light to the one who has do desire or longing for it and who is utterly lost in worldly pursuits and in seeking material pleasures and gains. This bounty can be bestowed only on the one who in the knowledge of Allah has a sincere desire for it”.
Therefore the name of this site, i intend it to be the Misykat, pearl-like star, a niche light, but it may, if Allah’s will, brighten the universe.
