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).
Tazkirul Quran
Maulana Wahiduddin KhanOn ayahs 15–17
The Book of God is not a mere book in the ordinary sense of the word. It is in fact a reminder. It is to remind man that the creation of mankind in the present world was not an accident. It took place in accordance with a divine plan, by which man was to be given temporary freedom for the purpose of putting him to the test, and thereafter rewarding him according to his deeds in this world. A partial manifestation of this fact has been given time and again in the shape of the destruction of transgressing communities. Its full manifestation will take place on the Day of Reckoning, when all past and present human beings will be re-created and gathered together in God’s court. As long as man possesses material means of support, he is not prepared to come out of his slumber of carelessness. But when the process of God’s reckoning starts, all the material props on the strength of which the individual dared to ignore the call for Truth, will appear to be so burdensome that he would like to get rid of them. And it is only when he has to part company with his props that his eyes are opened. However, the opening of his eyes at that juncture will be of no avail, because at that time all things will have lost their power. Thereafter, only God and not the false deities—will have the power to help.
