Allah created universe as the same number number of earth. Earth is created with seven layers. It has been being said by prophet Muhammad S.A.W.
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.” (Saheeh Al-Bukhari,
‘Book of Oppression.’)
It's true. The geologist have proven that. Here are the layers of earth as geologists have proven:
(1) The Solid Inner Core of Earth: 1.7% of the
Earth’s mass; depth of 5,150 - 6,370 kilometers (3,219 - 3,981 miles)
(2) The Liquid Outer core: 30.8% of Earth’s mass;
depth of 2,890 - 5,150 kilometers (1,806 - 3,219 miles)
3) The “D” Layer: 3% of Earth’s mass; depth of
2,700 - 2,890 kilometers (1,688 - 1,806 miles)
(4) Lower Mantle: 49.2% of Earth’s mass; depth of
650 - 2,890 kilometers (406 -1,806 miles)
(5) Middle Mantle (Transition region): 7.5% of
Earth’s mass; depth of 400 - 650 kilometers (250-406 miles)
(6) Upper Mantle: 10.3% of Earth’s mass; depth of
10 - 400 kilometers (6 - 250 miles)
(7) Lithosphere
SUbhanallah. How beautiful islam is.
