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.

The Disbelievers' Hatred for Salih
At first, the people of Thamud 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 Allah's signs. It lived among Salih's people, some of whom believed in Allah while the majority continued in their obstinacy and disbelief.
Their hatred of Salih turned towards the blessed she-camel and became centered on it. A conspiracy started to be hatched against the camel by the disbelievers, and they secretly plotted against it.
Salih feared that they might kill the camel, so he warned them: "0 my people! This she-camel of Allah is a sign to you, leave her to feed on Allah's earth, and touch her not with evil, lest a near torment will seize you." Surah 11: 64
For a while, Salih's 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 Salih's followers, and they clung to their belief in Allah.

The Disbelievers' Plot to Kill the She-Camel
The disbelievers now began complaining that this huge she-camel with its unusual qualities drank most of the water and frightened their cattle.
They laid a plot to kill the camel, and sought the help of their women-folk to tempt the men to carry out their commands. Saduq Bint of Mahya, who was from a rich and noble family, offered herself to a young man named Masra'i Ibn Mahraj on condition that he hamstring the camel. Aniza, an old woman, offered one of her daughters to a young man, Qudar Ibn Saluf, in return for killing the camel. Naturally these young men were tempted and set about finding seven others to assist them.
They watched the camel closely, observing all its movements. As the she-camel came to drink at the well, Masrai shot it in the leg with an arrow. It tried to escape but was hampered by the arrow. Qudar followed the camel and struck it with a sword in the other leg. As it fell to the ground, he pierced it with his sword.
