115. The people of Aiykah have been briefly mentioned in verses 78-84 of Surah Al-Hijr. More about them here. There is a difference of opinion among the commentators as to whether the Midianites and the people of Aiykah were two different tribes or one and the same people. One group holds that they were different tribes and gives the argument that in Surah Al-Aaraf Prophet Shuaib (peace be upon him) has been brother of the Midianites (verse 85), whereas here, with regard to the people of Aiykah, he has not been called so. The other group holds that they were one and the same people on the ground that the moral diseases and characteristics mentioned of the Midianites in Surahs Al-Aaraf and Houd are the same as of the people of Aiykah mentioned here. Then the message and admonition of Prophet Shuaib (peace be upon him) to both the tribes was the same, and the two tribes also met the same end.
Research in this regard has shown that both the views are correct. The Midianites and the people of Aiykah were doubtless two different tribes but branches of the same stock. The progeny of Prophet Abraham (peace be upon him) from his wife (or slave girl) Keturah, is well known in Arabia and in the history of the Israelites as the children of Keturah. Their most prominent branch was the one which became famous as the Midianites, after their ancestor, Midian, son of Abraham. They had settled in the territory between northern Arabia and southern Palestine, and along the coasts of the Red Sea and the Gulf of Aqabah. Their capital city was Madyan, which was situated, according to Abul Fida, on the western coast of the Gulf of Aqabah at five days’ journey from Aiykah (present day Aqabah). The rest of the children of Keturah, among whom the Dedanites are comparatively better known, settled in the territory between Taima and Tabuk and Al-Ula in northern Arabia, their main city being Tabuk, the Aiykah of the ancient times. (Yaqut in his Mujam al-Buldan, under Aiykah, writes that this is the old name of Tabuk, and the natives of Tabuk confirm this).
The reason why one and the same Prophet was sent to the Midianites and the people of Aiykah was probably that both the tribes were descendants of the same ancestors, spoke the same language and had settled in the adjoining areas. It is just possible that they lived side by side in the same areas and had marriages and other social relations between them. Then, these two branches were traders by profession and had developed similar evil practices and social and moral weaknesses. According to the early books of the Bible, these people worshiped Baal-peor. When the Children of Israel came out of Egypt and entered their territory, they also became infected with the evils of idolatry and adultery. (Numbers, 25: 1-5, 31: 16-17). Then those people had settled on the two main international trade routes, the one joining Yaman with Syria and the other the Persian Gulf with Egypt. Due to their advantageous position they had started big scale highway robbery and would not let any caravan pass till it had paid heavy taxes. They had thus rendered these trade routes highly unsafe. Their characteristic of highway robbery has been mentioned in the Quran, for which they were admonished through Prophet Shuaib (peace be upon him), thus: And do not lie in ambush by every path (of life) as robbers in order to frighten the people (Surah Al-Aaraf, Ayat 86). These were the reasons why Allah sent to both the tribes the same Prophet, who conveyed to them the same teachings and message. For the details of the story of Prophet Shuaib (peace be upon him) and the Midianites, see (Surah Al-Aaraf, Ayats 85-93); (Surah Houd, Ayats 84-95); and (Surah Al-Ankabut, Ayats 36-37).
116. That is, it is not in my power to bring down the torment; it is in Allah’s power, and He is fully aware of your misdeeds. He will send down the torment as and when He wills. In this demand of the people of Aiykah and the answer of Prophet Shuaib (peace be upon him) to them there was an admonition for the Quraish as well. They also demanded from the Prophet (peace be upon him) to bring down the torment on them: Or.... you cause the sky to fall down on us in fragments, as you threaten us. (Surah Bani Israil, Ayat 92). As such the Quraish are being told that the people of Aiykah had also demanded a similar thing from their Prophet, and the answer that they got from their Prophet is the answer of Muhammad (peace be on him) to you.
117. The details of this torment are neither found in the Quran nor in any authentic tradition. What one can learn from the text is this: As these people had demanded a torment from the sky, Allah sent upon them a cloud which hung over them like a canopy and kept hanging until they were completely destroyed by the torment of continuous rain. The Quran clearly points out that the nature of the torment sent upon the Midianites was different from that sent upon the people of Aiykah. The people of Aiykah, as mentioned here, were destroyed by the torment of the canopy, while the torment visiting the Midianites was in the form of a terrible earthquake: It so happened that a shocking catastrophe overtook them and they remained lying prostrate in their dwellings. (Surah Al-Aaraf, Ayat 91). And: A dreadful shock overtook them and they lay lifeless and prostrate in their homes. (Surah Houd, Ayat 94). Therefore, it is wrong to regard the two torments as identical. Some commentators have given a few explanations of the torment of the Day of canopy, but we do not know the source of their information. Ibn Jarir has quoted Abdullah bin Abbas as saying: If somebody from among the scholars gives you an explanation of the torment of the Day of canopy, do not consider it as correct.
