These verses describe the destruction of those settlements which some exegesists have taken as Fladhura' ) حضُوراء) and Qilabah (قلابہ) of Yemen. Allah Ta` ala had sent there a prophet about whose name there are different versions. Some say he was Musa Ibn Misha while others say his name was Shu` aib, in which case he was a different prophet from the one who lived in Madyan. This Prophet was killed by his people, who were, as a punishment annihilated by the infidel King Nabucad Nazzar.
This King was placed in authority over them just as he was used as an instrument for the punishment of Bani Isra'i1 when they strayed from the righteous path in Palestine. In fact, Qur'an has not identified any specific settlement. Hence it will be apt to leave the subject open, so that these settlements of Yemen may also come in its ambit. واللہ (Only Allah knows best).
