Sūrah Hūd Alahi Wa Salam [(Prophet) Hūd) XI : Ayāt 62:

They answered: "Yes."

So he took a vow from them on this, then prayed to Allāh Subhanahu Wa Ta'ala to grant their request. Allāh Subhanahu Wa Ta'ala ordered the distant rock to split asunder, bringing forth a great ten-month-pregnant she-camel. When their set eyes on it, they were amazed. They saw a great thing, a wonderful sight, dazzling power, clear evidence!

A number of Sāleh's Alahi Wa Salam people believed, yet most of them continued in their disbelief, stubbornness and going astray. Allāh Subhanahu Wa Ta'ala said:

Sūrah Al-Isrā' (The Journey by Night) XVII : Ayāt 59;

and also:

Sūrah Al-Hijr (The Rocky Tract) XV : Ayāt 80 & Ayāt 81;

There are a number of ancient accounts of this camel and its miraculous nature. It was said that the she-camel was miraculous because a rock in the mountain split open and it came forth from it, followed by its young offspring. Other accounts said that the she-camel used to drink all the water in the wells in one day, and no other animals could approach the water. Still others claimed that the she-camel produced milk sufficient for all the people to drink, on the same day that it drank all the water, leaving none for them.

At first, the people of Thamūd were greatly surprised when the she-camel issued from the mountain rocks. It was a blessed camel, its milk sufficient for thousands of men, women and children. If it slept in a place, that place was abandoned by other animals. Thus it was obvious that it was not an ordinary camel, but one of Allāh's Subhanahu Wa Ta'ala signs. It lived among Sāleh's Alahi Wa Salam people, some of whom believed in Allāh Subhanahu Wa Ta'ala while the majority continued in their obstinacy and disbelief.

Their hatred of Sāleh Alahi Wa Salam turned towards the blessed she-camel and became centred on it. A conspiracy started to be hatched against the camel by the disbelievers, and they secretly plotted against it. Sāleh Alahi Wa Salam feared that they might kill the camel, so he warned them:

Sūrah Hūd Alahi Wa Salam [(Prophet) Hūd) XI : Ayāt 64;

For a while, Sāleh's Alahi Wa Salam people let the camel graze and drink freely, but in their hearts they hated it. However, the miraculous appearance of the unique camel caused many to become Sāleh's Alahi Wa Salam followers, and they clung to their belief in Allāh Subhanahu Wa Ta'ala.

Allāh Subhanahu Wa Ta'ala related their story:

Sūrah An-Naml [(The Ants) XXVII: Ayāt 45 till Ayāt 53;

Allāh Subhanahu Wa Ta'ala saved Sāleh Alahi Wa Salam and his followers from their wicked plans. Heavy-hearted, they left the evil-doers and moved to another place. Three days after Sāleh's Alahi Wa Salam warning, thunderbolts filled the air, followed by severe earthquakes which destroyed the entire tribe and its homeland. The land was violently shaken, destroying all living creatures in it. There was one terrific cry which had hardly ended when the disbelievers of Sāleh's Alahi Wa Salam people were struck dead, one and all, at the same time. Neither their strong buildings nor their rock-hewn homes could protect them.

Allāh Subhanahu Wa Ta'ala said:

Sūrah Al-A'rāf [The Height (or The Wall with Elevations)] VII : Ayāt 73 till 79;

All were destroyed before they realized what was happening. As for the people who believed in the message of Sāleh Alahi Wa Salam, they were saved because they had left the place.  Ibn 'Umar narrated that while the Prophet Muhammad Sallallahu ‘Alaihi Wa Sallam was passing by Thamūd's houses on his way to the battle of Tabūk, he stopped together with the people there. The people fetched water from the wells from which the people of Thamūd used to drink. They prepared their dough (for baking) and filled their water-skins from it (the water from the wells).

The Prophet Sallallahu ‘Alaihi Wa Sallam of Allāh Subhanahu Wa Ta'ala ordered them to empty the water-skins and give the prepared dough to the camels. Then he went away with them until they stopped at the well from which the she-camel (of Sāleh Alahi Wa Salam,) used to drink. He warned them against entering upon the people that had been punished, saying: "I fear that you may be affected by what afflicted them; so do not enter upon them."
