Kayak ginilah iptek Islam, hehehe...
Tabari I:219 "When Allah wanted to create the creation, He brought forth smoke from the water. The smoke hovered loftily over it. He called it 'heaven.' Then He dried out the water and made it earth. He split it and made it seven earths on Sunday. He created the earth upon a big fish, that being the fish mentioned in the Qur'an. By the Pen, the fish was in the water. The water was upon the back of a small rock. The rock was on the back of an angel. The angel was on a big rock. The big rock was in the wind. The fish became agitated. As a result, the earth quaked, so Allah anchored the mountains and made it stable. This is why the Qur'an says Allah made for the earth 'firmly anchored mountains, lest it shake you up.'"
