concept of Seven Earth is Mention in Holy Qur'an is proved by science

The Prophet Muhammad(S.W.A.L) is the second revealed source of Islam.  Like the Quran,It is the book of miracles it contains scientific information unavailable 1400 years ago.  From these miracles is the “seven” earths, mentioned by the Prophet in several of his sayings.  From them are the following two:
Hadith 1
It was narrated on the authority of Abu Salamah that a dispute arose between him and some other people (about a piece of land).  When he told Aisha (the Prophet’s wife) about it, she said, ‘O Abu Salamah!  Avoid taking the land unjustly, for the Prophet said:“Whoever usurps even one span of land of somebody, its depth through the seven earths will be collared to his neck.” (Saheeh Al-Bukhari, ‘Book of Oppression.’)
Hadith 2
Salim narrated on the authority of his father that the Prophet said“Whoever takes a piece of land of others unjustly, he will sink down the seven earths on the Day of Resurrection.”

1) The Solid Inner Core of Earth: depth of 5,100 - 6,378 kilometers (3,219 - 3,981 miles)
(2) The Liquid Outer core: depth of 2,900 - 5,100 kilometers (1,806 - 3,219 miles)
(3) The “D” Layer: depth of 2,700 - 2,900 kilometers (1,688 - 1,806 miles) This layer is 200 to 300 kilometers (125 to 188 miles) thick
(4) Lower Mantle: depth of 650 - 2,890 kilometers (406 -1,806 miles)
(5) Middle Mantle (Transition region): depth of 400 - 650 kilometers (250-406 miles)
(6) Upper Mantle: depth of 10 - 400 kilometers (6 - 250 miles)
(7) Lithosphere Oceanic crust: depth of 0-10 kilometers (0 - 6 miles)
It must be remembered that according to science all these layers are made of different substances and material; hence the Holy Quran expression of seven earths must be considered in this context, since these are seven different parts of the earth. As stated earlier, the word ardh (earth) refers to a ‘tract of land’. The second logical possibility is that six other planets like our own earth do really exist. This, too, has recently been proven by science exploration of the universe.
