Madain Sahreha means 'Town of Sahreha.'
Once in a while, before Muhammad, there was a prophet among Thamud people.
Allah gave Thamuds sacrid camels and Sahreha told the people to take care of them. However, the Thamuds refused it and killed the camels.
Then, Allah killed the people of Thamud except Sahreha and his followers.
Modern Madain Sahreha is a kind of tourism attraction, but still it's a cursed land for Muslims.
