Surah 29. Al-Ankabut, Ayah 35

This is an allusion to the Dead Sea - known to this day as Bahr Lut ("The Sea of Lot") - which covers most of the region in which Sodom and Gomorrah were once situated. Its waters contain so high a percentage of sulphur and potash that no fish or plants can live in them.

The whole tract on the east side of the Dead Sea (where the Cities were situated) is covered with sulphureous salts and is deadly to animal and plant life. The Dead Sea itself is called in Arabic the Bahr Lut (the sea of Lot). It is a scene of utter desolation, that should stand as a Symbol of the Destruction that awaits Sin.
