Quran speaks in detail about scientific facts which have discovered recently.. There are lot of examples for it..
Quran speak about BIG BANG & BIOLOGY 1400 years ago which science discovered recently, Quran says "Do not the unbelievers see that the heavens and the earth were joined(as one unit of creation),before we clove them asunder? we made from water every living thing, will they not them believe?" (21:30)..
Allah says in the Quran that MOON HAS IT'S REFLECTED LIGHT which science discovered recently, Quran says "Blessed is He who made constellations in the skies, and placed therein a lamp and a moon giving light" (25:61)..
Science discovered recently that PLANTS ARE PERSEXIVE i.e plant have sex(male and female) n it's mentioned in the Quran in Sure- Taha "With it have we produced diverse pairs of plants each seperate from the others" (20:53)..
It's very recently that science discovered that the SUN REVOLVE IN IT'S ORBIT.. Earlier it was a belief that sun rotate,but does'nt revolve, science discovered recent fact by copying it from the versus of Sure Ambiya, Quran says "It is He who created the night and the day, and the sun and the moon: all(the calestial objects) swim along,each in it's rounded course" (21:33).. From the above verse it's clear that every calestial object revolve in their respective orbits..
The astronomist declared that UNIVERSE IS EXPANDING, Quran says same 14 centuries ago in Chapter 51, "We have built the firmament wit might: and we indeed have vast power. And we spread out the (spacious) earth: how exellently we do spread out" (51:47&48)..
Science discovered that there are TWO TYPES OF WATER in the sea and there is barrier between them, but the same fact Quran says more then thousand years ago, In Sure- Bani Israel "It's He who has let free the two bodies of flowing water: one palatable and sweet, and the other salt and bitter; yet has he made a barrier between them, a partition that is not to be passed" (17:57) and also in Sure- Rehman "He has let free the two seas, meeting together. Between them is a barrier which they do not transgress" (55:19&20)..
Science says EARTH DO NOT SHAKE BECAUSE OF MOUNTAINS, Quran says "Have we not made the earth as a wide expanse. And the mountain as pegs" (78:6&7)
This are the clear proofs for accuracy of the Holy Quran, who could have mentioned that facts 14 centuries ago, it's none other than Allah who created this universe and who have best knowledge of all..
