About the city:
Mada'in Salih is identified by Muslims with the story of the prophet Salih in the Koran. This concerns a prophet whose teaching was rejected by the people to whom he was sent, with the result that their city was destroyed by a natural calamity.
According to quran, when the people of Thamud refused to listen to the prophet's words, they proposed that at a certain festival they should pray to their gods and he to his, and see which would answer. When the day came the Thamudites first prayed to their idols, with no result. Then their prince, Jonda, challenged Salih to conjure forth a she-camel, big with young, from the rocks nearby and swore that if the prophet brought this miracle to pass they would believe him.Salih asked it of God. The rocks shuddered as though in labour and a she-camel came forth, big with young. Seeing the miracle, Jonda believed, and some few with him; but the rest of the Thamudites still repudiated the prophet and glorified their own idols.
Meanwhile the miraculous she-camel drank up all the water from the village well, but at the same time she produced inexhaustible supplies of milk. Some commentators say that she went through the village streets crying, "If any wants milk, let him come forth!" This caused both wonder and dismay, for although the people appreciated the milk they feared for their supply of water. Finally, although Salih begged them to spare the she-camel if they hoped to avert the wrath of God, the Thamudites lamed the miraculous animal by cutting her tendons, and then killed her. Her young foal, however, came forth from the womb unharmed and vanished into a great rock .Then Salih warned the people to stay inside their houses for three days. And on the third day "a terrible noise from heaven assailed them; and in the morning they were found in their dwellings prostrate on their breasts and dead."
