He made this dua in the darkness of the whale's stomach, in the darkness of the ocean, and in the darkness of the night.-
Angels see circles of remembrance of Allah just like we see the stars in the sky. They saw a light coming from the ocean and they recognized the voice of Yunus.- The Angels asked Allah: "Isn't this the voice of your righteous servant who used to do good by day and night?"... The angels then made dua for Yunus that Allah would release him.- Allah says: "If it wasn't for the fact that he used to remember us, he would have remained in the stomach of the whale until the day of judgment"- We need to remember Allah in moments of goodness so He would remember us in our times of need.
35.*Allah is the Light of the heavens and the earth. The Parable of His Light is as if there were a Niche and within it a Lamp: the Lamp enclosed in Glass: the glass as it were a brilliant star: Lit from a blessed Tree, an Olive, neither of the east nor of the west, whose oil is well-nigh luminous, though fire scarce touched it: Light upon Light! Allah doth guide whom He will to His Light: Allah doth set forth Parables for men: and Allah doth know all things.
36.*(Lit is such a Light) in houses, which Allah hath permitted to be raised to honour; for the celebration, in them, of His name: In them is He glorified in the mornings and in the evenings, (again and again),
-37.*By men whom neither traffic nor merchandise can divert from the Remembrance of Allah, nor from regular Prayer, nor from the practice of regular Charity: Their (only) fear is for the Day when hearts and eyes will be transformed (in a world wholly new),
-38.*That Allah may reward them according to the best of their deeds, and add even more for them out of His Grace: for Allah doth provide for those whom He will, without measure.
Quran Chapter 24
i believe it is possible to use a popular software and search engine such as google to make a global image of where Islam is practised most - even down to city blocks using pan zoom and tilt.
it wouldn't be as accurate as the way the angels see it even in remote areas without internet etc, but it would be interesting to view.
