The detailed description of these seven earths is given by Muhammad ibn 'Abd Allah al-Kisa'i:
%u201C... There are seven earths.
1.The first is called Ramaka, beneath which is the Barren Wind, which can be bridled by no fewer than seventy thousand angels. With this wind God destroyed the people of Ad. The inhabitants of Ramaka are a nation called Muwashshim, upon whom is everlasting torment and divine retribution.
2.The second earth is called Khalada, wherein are the implements of torture for the inhabitants of Hell. There dwells a nation called Tamis, whose food is their own flesh and whose drink is their own blood.
3.The third earth is called Arqa, wherein dwell mulelike eagles with spearlike tails. On each tail are three hundred and sixty poisonous quills. Were even one quill placed on the face of the earth, the entire universe would pass away. The inhabitants thereof are a nation called Qays, who eat dirt and drink mothers' milk.
4.The fourth earth is called Haraba, wherein dwell the snakes of Hell, which are as large as mountains. Each snake has fangs like tall palm trees, and if they were to strike the hugest mountain with their fangs it would be leveled to the ground. The inhabitants of this earth are a nation called Jilla, and they have no eyes, hands or feet but have wings like bats and die only of old age.
5.The fifth earth is called Maltham, wherein stones of sulphur hang around the necks of infidels. When the fire is kindled the fuel is placed on their breasts, and the flames leap up onto their faces, as He hath said: The fire whose fuel is men and stones (2:24), and Fire shall cover their faces (14:50). The inhabitants are a nation called Hajla, who are numerous and who eat each other.
6.The sixth earth is called Sijjin. Here are the registers of the people of Hell, and their works are vile, as He hath said: Verily the register of the actions of the wicked is surely Sijjin (83:7). Herein dwells a nation called Qatat, who are shaped like birds and worship God truly.
7.The seventh earth is called Ajiba and is the habitation of Iblis. There dwells a nation called Khasum, who are BLACK and short, with claws like lions. It is they who will be given dominion over Gog and Magog, who will be destroyed by them%u2026 [8]
THIS PROVES THAT ISLAM IS NOT ANY MORE AUTHENTIC THAN 'HARRY POTTER' OR 'LORD OF THE RINGS'
