Pumice

Geology - Intermediate

Least dense stone on Earth.

1400 years ago nobody knew that pumice was the least dense stone on Earth however this was portrayed in the Quran.

The Quran portrays birds carrying pumice for long distances and hitting the enemy. Skeptics claim that whoever wrote the Quran made a mistake; those stones are too heavy to be carried by the birds. Today geologists confirm that pumice is so light that it can even float on water.

Pumice stone are the least dense stone on Earth. This was known recently, however this was portrayed in the Quran 1400 years before it was discovered:

Quran 105:3-4

He sent against them swarms of birds. Throwing at them rocks of pumice.

٣ وَأَرْسَلَ عَلَيْهِمْ طَيْرًا أَبَابِيلَ
٤ تَرْمِيهِمْ بِحِجَارَةٍ مِنْ سِجِّيلٍ

Pumice "Sijjeel in Arabic سِجِّيلٍ" is also found in Quran 15:74 where the city was showered by a volcano. Today we know that pumice is very porous and has very low density which means it is very easy for the birds to carry.

How could an illiterate man who lived 1400 years ago have known about pumice?
