Genealogy — From Nuh to Salih
According to al-Tabari’s “History of Prophets and Kings” — drawing on Ibn Ishaq’s genealogical tradition — the lineage of Salih (AS) runs:
Salih ibn ‘Ubayd ibn Asif ibn Masikh ibn ‘Ubayd ibn Khadir ibn Thamud ibn ‘Athir ibn Iram ibn Sam ibn Nuh
Thus Salih was a direct descendant of:
- Nuh (Noah) — the prophet of the flood
- Sam (Shem) — Nuh’s eldest son, ancestor of the Semitic peoples
- Iram — from whom came both the ‘Ad (through ‘Aws, connected to Hud’s people) and the Thamud
- Thamud — the eponymous ancestor of the people to whom Salih was sent
The Thamud are thus kinsmen of the ‘Ad — both descended from Sam ibn Nuh through Iram. The Quran confirms this: “And remember when He made you successors after the ‘Ad and settled you in the land, [and] you take for yourselves palaces from its plains and carve from the mountains, homes.” (7:74)
The People of Thamud — Rock-Carvers of Arabia
The Thamud were successors to the ‘Ad — they came after the ‘Ad’s destruction and inherited their role as the great power of the Arabian Peninsula. Where the ‘Ad were known for their height and power, the Thamud were known for their architectural skill:
“And [We sent] to Thamud their brother Salih. He said: ‘O my people, worship Allah; you have no deity other than Him. He has produced you from the earth and settled you in it, so ask forgiveness of Him and then repent to Him. Indeed, my Lord is near and Responsive.’” (11:61)
The rock cities of Thamud: The Quran’s description of the Thamud as builders who “carve from the mountains, homes” (7:74) corresponds precisely to an archaeological reality: the ancient city of Al-Hijr (modern Mada’in Salih in northwest Saudi Arabia, known in ancient times as Hegra) preserves hundreds of monumental rock-carved tombs and dwellings from the Nabataean period — and earlier Thamudic inscriptions and architectural remains have been found in the same region. The Thamud are mentioned in Assyrian records as early as 715 BCE.
Al-Hijr (also called Wadi al-Qura in early Islamic usage) was a famous waypoint on the trade routes from Arabia to the Levant. The Prophet Muhammad (SAW) is recorded as passing by it during the Tabuk expedition (9 AH) and instructing his companions not to drink from its wells or use its structures — treating it as a place of divine punishment, as the Quran describes.
The She-Camel — The Divine Sign
The most distinctive element of Salih’s story is the naqat Allah (she-camel of Allah) — a miraculous sign given to the Thamud as proof of Salih’s prophetic mission:
“And O my people, this is the she-camel of Allah — [she is] a sign for you. So let her graze upon Allah’s earth and do not touch her with harm, or you will be taken by a swift punishment.” (11:64)
“And We have sent to Thamud their brother Salih, [saying]: ‘Worship Allah.’ But they became two parties in disagreement. He said: ‘O my people, why do you hasten the evil before the good? Why do you not seek forgiveness of Allah that you may receive mercy?’ They said: ‘We consider you a bad omen, you and those with you.’ He said: ‘Your omen is with Allah. Rather, you are a people being tested.’” (27:45-47)
The terms of the test: The she-camel was given specific protection:
- She was to graze freely on Allah’s earth — not to be restricted or penned
- She was to have access to water — on the alternating day, she drank and the Thamud were not to use the water source
- She was not to be harmed — any harm to her would trigger the divine punishment
The deeper meaning of the she-camel: Islamic commentators have noted that the she-camel was not just a sign but a test of the Thamud’s relationship to the divine’s command. The divine did not make her difficult to follow — she simply required them to let her be. The test was whether they could accept the one divine limitation placed on their unrestricted use of their land.

The Conspiracy and the Killing
“Then they called their companion, and he dared and hamstrung [her]. And how [severe] was My punishment and warning.” (54:29)
The Thamud’s destruction of the she-camel was not spontaneous but organized:
The Quranic account: A specific person (or group) was commissioned by the community leadership to hamstring (‘aqara) the she-camel. The responsibility is shared: “we called their companion” — the community collectively endorsed what the individual did. This is significant: the Quran does not present the killing as a lone criminal act but as a community decision.
The person who killed her: Islamic tradition identifies the one who hamstrung the she-camel as Qidar ibn Salif (or Musday’a ibn Mahraj), described as a powerful, red-faced, and blue-eyed man — a figure of physical imposing character who was respected enough in the community to carry out this act.
The motivation for killing her: The Quran gives a hint: “They hamstrung her and were defiant of the command of their Lord.” The defiance is not random — it is the Thamud’s assertion of their own sovereignty against the divine’s restriction. The she-camel represented a limit on their complete control of their land, and they refused that limit.
Salih’s Warning — Three Days
After the killing, Salih gave his people the divine warning:
“He said: ‘Enjoy yourselves in your homes for three days [then will come the punishment]. That is a promise not to be denied.’” (11:65)
Three days of grace: Unlike some prophetic communities who received punishment immediately, the Thamud received three days of warning. This reflects the divine’s hilm (forbearance) — the willingness to give even those who have committed the unforgivable sin a final opportunity. During these three days, the Thamud could theoretically have repented.
The behavior of the Thamud during the three days: Islamic tradition records that the Thamud did not repent but instead doubled down — they plotted to kill Salih himself (27:48-49): “And there were in the city nine family heads causing corruption in the land and not amending. They said: ‘Swear by Allah that we will kill him and his family by night.’”
The Punishment — The Sayha
“And when Our command came, We saved Salih and those who believed with him, by mercy from Us, and [saved them] from the disgrace of that day. Indeed, it is your Lord who is the Powerful, the Exalted in Might. And the shriek (al-sayha) seized those who had wronged, and they became within their homes [corpses] fallen prone.” (11:66-67)
The punishment was al-sayha (the blast/shriek) — a devastating sound that destroyed all life. This is the same punishment that struck the people of Shu’ayb (Madyan). The sound of the divine’s punishment is so devastating that it kills instantly.
“And they were overtaken by the punishment at sunrise.” (15:83) — The timing: sunrise, the moment of light and new day, became the moment of their destruction. The Thamud who had defied the divine’s sign met the divine’s power at the dawn.
Salih and the believers: Salih and the community of believers were saved — removed from the region before the punishment came. Islamic tradition holds that Salih then moved northward, living out his life among communities in Palestine/Canaan, and died there.
Archaeological Correspondence
Mada’in Salih (the “Cities of Salih”) in the Tabuk region of northwest Saudi Arabia preserves approximately 111 monumental rock-carved tombs and extensive Thamudic/Nabataean inscriptions. UNESCO designated it a World Heritage Site in 2008. While the archaeological remains visible today are primarily Nabataean (1st century BCE to 1st century CE), they overlie much earlier Thamudic settlement layers that correspond to the Quranic narrative’s timeframe.
The Prophet’s instruction not to use Mada’in Salih’s water or dwellings during the Tabuk expedition, and his visible grief while passing through it, is recorded in Sahih Bukhari and Muslim — reflecting the Islamic treatment of sites of divine punishment as places of solemn reflection.
The Prophets’ Genealogical Tree — Adam to the Thamud
The prophets of the Quran connected to the pre-Abrahamic Arab peoples form a distinct strand of the prophetic tradition:
Adam → Shith → Idris → Nuh → Sam → Iram → ‘Ad branch → Hud Adam → Shith → Idris → Nuh → Sam → Iram → Thamud branch → Salih Adam → Shith → Idris → Nuh → Sam → Arfakhshad → Shalakh → ‘Abir → Faligh → Ra’u → Sarukh → Nahor → Tareh → Ibrahim
This tree, drawn from al-Tabari’s compilation of Ibn Ishaq and earlier genealogical sources (from the 101P.pdf genealogy of the prophets), shows the Arabic and Semitic prophets as part of a single continuous family from Adam. Each prophet in this chain was sent to their own people — their own branch of the family — with the same core message of tawhid.

Ta’wil of Salih’s Message
The zahir of Salih’s story is the account of a civilization that received a divine sign (the she-camel), was given a single restriction (do not harm her), violated that restriction out of defiance, and was destroyed three days later.
The batin of Salih’s story is the perennial human challenge of accepting the divine’s one restriction on human freedom. The Thamud were not destroyed for being evil generally — they were destroyed for violating one specific divine command, the one that directly represented the divine’s authority in their lives.
In the Ismaili ta’wil, the she-camel corresponds to the walayah of the Imam in each era: the divine places one specific sign in the world — the living Imam (in each era, the Da’i carries this presence) — and commands that this sign be honored, protected, and followed. The human community that rejects, hamstrings, or destroys this sign has committed the Thamudic error.
The three days of warning before the punishment correspond to the three opportunities every soul is given: in youth (when it first hears the call), in maturity (when it is tested by life’s demands), and in old age (when death approaches). The Thamud had their three days; every soul has its three opportunities.
“The she-camel of Allah — [she is] a sign for you.” (11:64) — In every era, the divine places among the community a sign: one who carries the divine’s ‘ilm, one who is to be followed with genuine walayah. This is the sign. To honor it is the Thamud’s lesson; to hamstring it is the Thamud’s tragedy.
