Wa-ila thamooda akhahum salihan qala ya qawmi oAAbudoo Allaha ma lakum min (surah Araf: 73)

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(7:73) And to Thamud *57 We sent forth their brother. Salih. He said to them: '0 my people! Serve Allah, you have no other god than Him. Truly there has come to you a clear proof from your Lord. This she-camel from Allah is a Divine portent for you. *58 So leave her alone to pasture on Allah's earth, and touch her with no evil lest a painful chastisement should seize you.

Wa ilaa Samooda akhaahum Saalihaa; qaala yaa qawmi` budul laaha maa lakum min ilaahin ghairuhoo qad jaaa`atkum baiyinatum mir Rabbikum haazihee naaqatul laahi lakum Aayatan fazaroohaa taakul feee ardil laahi wa laa tamassoohaa bisooo`in fa yaakhuzakum `azaabun aleem

*57). The Thamud are another ancient Arab people, next only to the 'Ad in fame. Legends relating to them were quite popular in pre-Islamic Arabia. In fact poetry and orations of the pre-Islamic (Jahiliyah) period abound with references to them. They are also mentioned in the Assyrian inscriptions and in the Greek, Alexandrian and Roman works of history and geography. Some descendants of the Thamud survived to a little before the birth of Jesus. The Roman historians mention that they entered into the Roman army and fought against the Nabateans, their arch-enemy.
The Thamud lived in the north-western part of Arabia which is still called al-Hijr. In the present time there is a station on the Hijaz railway, between Madina and Tabuk. This is called Mada'in Salih, which was the capital town of Thamud and was then known as al-Hijr, the rock-hewn city. This has survived to this day and is spread over thousands of acres. It was once inhabited by no less than half a million people. At the time of the revelation of the Qur'an Arab trade caravans passed through the ruins of this city.
While the Prophet (peace be on him) was on his way, to Tabuk, he directed the Muslims to look upon these monuments and urged them to learn the lessons which sensible persons ought to learn from the ruins of a people that had been destroyed because of their evil-doing. The Prophet (peace be on him) also pointed to the well from which the she-camel of the Prophet Salih used to drink. He instructed the Muslims to draw water from that well alone and to avoid all other wells. The mountain pass through which that she-camel came to drink was also indicated by the Prophet (peace be on him). The pass is still known as Fajj al-Naqah. The Prophet (peace be on him) then gathered all the Muslims who had been directed to look around that city of rocks, and addressed them. He drew their attention to the tragic end of the Thamud, who by their evil ways had invited God's punishment upon themselves. The Prophet (peace he on him) asked them to hastily move ahead for the place was a grim reminder of God's severe punishment and he hence called for reflection and repentance. (See waqidi, al-maghazi, vol. 3, pp. 1006-8. See also the comments of Ibn Kathir on verses 73-8 - Ed.)
*58). The context seems to indicate that the clear proof referred to in the verse stands for the she-camel which is also spoken of as 'a Divine portent'. In al-Shu'ara' 26: 154-8 it is explicitly mentioned that the Thamud themselves had asked the Prophet Salih to produce some sign which would support his claim to be God's Messenger. Responding to it, Salih pointed to the she-camel.
This illustrates clearly that the appearance of the she-camel was a miracle. Similar miracles had been performed earlier by other Prophets with a view to fulfilling the demand of the unbelievers and thus of vindicating their claim to prophethood. The miraculous appearance of the she-camel reinforces the fact that Salih had presented it as a 'Divine portent' and warned his people of dire consequences if they harmed it. He explained to them that the she-camel would graze freely in their fields; that on alternate days she and other animals would drink water from their well, They were also warned that if they harmed the she-camel they would be immediatelv seized by a terrible chastisemen' from God.
Such statements could obviously only have been made about an animal which was known to be of a miraculous nature. The Thamud observed the she-camel graze freely in their fields and she and the other camels drank water on alternate days from their well. The Thamud, though unhappy with the situation, endured this for quite some time. Later, however, after prolonged deliberations, they killed her. Such lengthy deliberations demonstrate that they were afraid to kill the she-camel. It is clear that the object of their fear was none other than the she-camel as they had no reason to be afraid of Salih, who had no power to terrify them. Their sense of awe for the she-camel explains why they let her graze freely on their land. The Qur'an, however, does not provide any detailed information as to what the she-camel looked like or how she was born. The authentic Hadith too provide no information about its miraculous birth. Hence, one need not take too seriously the statements of some of the commentators on the Qur'an about the mode of her birth. However, as far as the fact of her miraculous birth is concerned, that is borne out bv the Qur'an itself.
