It has been suggested that Petra in Jordan is the very Thamud to which the Prophet Salih was sent.
Assuming that Petra and Thamud are one in the same; let us examine recent findings from National Geographic – Petra:Ancient City of Petra Built to Align With the Sun:
These wealthy spice traders worshiped the sun, among other deities, and may have given importance to the equinoxes, solstices, and other astronomical events that are determined by how the sun moves across the sky.
Now keeping all of this in mind, let us go to Surah Shams(91) which in English means Sun:
1 By the sun and his brightness,
2 And the moon when she followeth him,
3 And the day when it revealeth him,
4 And the night when it enshroudeth him,
5 And the heaven and Him Who built it,
6 And the earth and Him Who spread it,
7 And a soul and Him Who perfected it
8 And inspired it (with conscience of) what is wrong for it and (what is) right for it.
9 He is indeed successful who causeth it to grow,
10 And he is indeed a failure who stunteth it.
11 (The tribe of) Thamud denied (the truth) in their rebellious pride,
12 When the basest of them broke forth
13 And the messenger of Allah said: It is the she-camel of Allah, so let her drink!
14 But they denied him, and they hamstrung her, so Allah doomed them for their sin and rased (their dwellings).
15 He dreadeth not the sequel (of events).
This is a miracle of the Qur’an . The Qur’an mentions Thamud within this surah, which is a confirmation that they are for sure, among those that worshipped the sun. Its amazing how the Qur’an confirms what modern archaeology has only recently discovered.
