From here the discourse is directed towards the hypocrites, who were bent upon starting mischief in the Islamic community, and were as active from within as the unbelievers were from without to harm the Islamic movement and the body politic of Islam. As these people professed belief, and apparently belonged to the Muslim community, and had blood relationships with the Muslims, especially with the Ansar, they were better placed to start and spread mischief. The result was that even some sincere Muslims, due to simplicity or weakness, became tools in their hands and even their supporters. But in spite of their profession of faith, the lure of worldly gains had utterly blinded them to the light that was spreading in the world through the teachings of the Quran and the Prophet Muhammad (peace be upon him). The indirect address to the hypocrites here has three things in view. Firstly, to admonish them, for the first and foremost demand of Allah’s providence and His mercy is to go on admonishing the misguided and the erring one till the last in spite of his persistence in mischief and wickedness. Secondly, to differentiate clearly between belief and hypocrisy so that every right thinking person from the Muslim community should be able to distinguish between a true believer and a hypocrite. Then if anybody, in spite of this differentiation, falls a prey to the machinations of the hypocrites or supports them, he should himself be responsible for his conduct.

Thirdly, to warn the hypocrites clearly and plainly that Allah’s promises for the believers are meant only for those who sincerely believe and then fulfill the demands and requirements of their faith. These promises are not meant for anybody who poses himself as a Muslim. The hypocrites and the sinful people therefore should not cherish any hope that they will have any share in these.

The phrase heavens and the earth in the Quran is generally used for the universe. Thus the verse would also mean: Allah is the light of the whole universe.

Light is something which makes things visible; which is itself manifest and helps make other things manifest. The human mind conceives light in this very sense. Absence of light is termed darkness, invisibility and obscurity. On the other hand, when there is visibility and things become exposed to view, man says there is light. Allah has been called Light' in this basic sense, and not in the sense of a beam of light which travels at the speed of 186,000 miles per second and stimulates the optic nerve through the retina. This conception of light has nothing to do with the reality of the meaning for which human mind has coined this word; rather the word light is used for all those lights which we experience in this physical world. All human words used for Allah are used in their basic sense and meaning, and not with reference to their physical connotation. For instance, when, the word sight is used with respect to Allah, it does not mean that Allah has an eye like men and animals with which He sees. Similarly when we say that Allah hears or grips or grasps, it does not mean that He hears through ears, or grips or grasps with the hand like us. These words are used in a metaphorical sense and only a man of very poor intelligence would have the misconception that hearing or seeing or grasping is not possible except in the limited and specific sense in which we experience it. Similarly it will be shortsightedness to interpret the word light in the sense of physical light rays emanating from a luminous body and affecting the retina. This word is not applicable to Allah in its limited sense, but in its absolute sense. That is, He alone in this universe is the real and prime cause of manifestation, otherwise there is nothing but darkness here. Everything which gives light and illuminates other things has received its light from Him; it has no light of its own.

The word light is also used for knowledge, and ignorance is termed as darkness. Allah is the Light of the universe in this sense too, because the knowledge of reality and of right guidance can be obtained from Him alone; without having recourse to His Light, there will be nothing but darkness of ignorance and the resultant vice and wickedness in the world.

"Blessed": yielding multiple benefits.

Which is neither in the east nor in the west: which grows in an open plane or on a hill, where it gets sunshine from morning till evening. Such an olive tree yields the oil which gives a bright light. On the other hand, a tree which gets sunlight only from the east or only from the west, yields thick oil which gives weak light.
