Prophet Hood was sent to the Aad people. Hood (Eber of the Bible) is said to be the grandson of Arphazed, the grandson of Nooh (Translation of Quran by Mohammad Alt, 90).
Allah says that to Aad (We sent) their brother Hood. He said:
"O my people serve Allah, you have no God other than Him. Will you not then guard against evil" (Aaraf 7:65): and, "O my people, I ask of you no reward for it. My reward is only with Him Who created me. Do you not then understand"? and, "O my people, ask forgiveness of your Lord, then turn to Him. He will send on you clouds puring down abundance of rain and add strength, and turn not back, guilty" (Hood, 11:51-53), and, "surely I am a faithful Messenger to you, so keep your duty to Allah and obey me, and keep your duty to Him who aids you with cattle and children, and gardens and fountains" (Shu'ara, 26:131-134).
The chiefs of the unbelievers said: certainly we see you in folly, and we certainly think you to be the liar (Aaraf, 7:66); and, 0 Hood, you have no clear argument, and we are not going to desert our gods for your word, and we are not believers in you; and we see not but that some of our gods have smitten you with evil. (Hood, II:53-54)
Hood said: O my people, there is no folly in me, but I am a Messenger of the Lord of the worlds. I deliver to you the Messages of my Lord and I am a faithful adviser to you. Do you wonder that a reminder has come to you from among you that he may warn you? And remember when He made you successors after Nooh's people and increased you in excellence of make. So remember the bounties of Allah, that you may be successful (Aaraf, 7: 67-69) and surely I call Allah to witness and you too bear witness that I am innocent of what you associate with Allah besides Him. So scheme against me all together, then give me no respite. Surely I put my trust in Allah, my Lord and your Lord. There is no living creature but He grasps it by its forelock. Surely my Lord is on the Right Path. But if you turn away, then indeed I have delivered to you that with which I am sent to you. And my Lord will bring another people in your place, and you cannot do Him any harm. Surely my Lord is the Preserver of all things (Hood, II:54-57) and surely I fear for you the chastisement of a Grievous Day (Shu'ara, 26:135).
They said: have you come to us that we may serve Allah alone, and give up that which our fathers used to serve? Then bring to us what you threaten us with, if you are of the truthful (Aaraf, 7:70). This is not but a fabrication of the ancients, and we will not be chastised (Shu'ara, 26:137-138).
Allah says: they rejected him, then We destroyed them (Shu'ara, 26: 139). They were overtaken by a curse in this world and on the Day of Resurrection (Hood. 11:60). As regards their destruction, Quran tells us: so when they saw a cloud advancing towards their valley, they said: this a cloud bringing us rain. Nay, it is that which you sought to hasten, a wind wherein is painful chastisement destroying every thing by the Command of its Lord. So at dawn nothing could be seen except their dwellings. Thus do we reward the guilty people (Ahqaf, 46:24-25). Quran further says: and as for Aad, they were destroyed by a roaring, violent wind, which Allah made to prevail against them for seven nights and eight days continuously, so that you might have seen the people therein prostrate as if they were trunks of hollow palm trees (Haaqqa, 69:6-7).
It is said that from amongst the Aad people, only 70 persons had accepted the Message of Hood and they all were saved from the disaster. It is their descendants who, later on, came to be known as the Second Aad or the Samood. The tomb of Prophet Hood is still traditionally shown in Hadhramaut about 90 miles north of Muk'alla. There are still ruins an inscription of the Aad time in the neighbourhood. There is an annual pilgrimage to the tomb of Hood in the month of Rajab.
After Aad the next nation that flourished on earth was known as Samood. They were the descendants of Samood, the son of Abir, the son of Sam, the son of Nooh. Thus they were the cousins to Aad. They flourished more than 200 years after Aad, and occupied the territory known as Al-Hijr (Hijr 15:80) and the plain known as Wadi-ul-Qura which forms the southern boundary of Syria and the northern one of Arabia (Mohammad Ali, ibid, 911). Thus their seat was in the North West corner of Arabia between Medina and Syria with their centre at Mada-in-e-Swaleh, which was known in their times as Hijr.
The Samood people excavated various rocks, and after having hewn and carved them, took up their abode therein. These rocks arc to this very day known by the name of Athalib (Mohammad Ali, ibid, 914). With the advance of material civilisation the Samood people became Godless and arrogant and were destroyed by earthquake.
