Reminding the Quraysh of the Destruction of earlier Disbelieving Nations
Allah the Exalted warns the disbelievers of Quraysh and reminds them of the punishment and painful torment that He sent in this life on their likes, who disbelieved before them. For instance, Allah the Exalted punished the people of Nuh by drowning them in the encompassing flood that touched all the people of earth. There is also the end that struck the people of Ar-Rass, and we mentioned their story before in Surat Al-Furqan,
وَثَمُودُوَعَادٌ وَفِرْعَوْنُ وَإِخْوَنُ لُوطٍ
(...and Thamud, and `Ad, and Fir`awn, and the brethren of Lut,) the people of Sadum (Sodom) and the surrounding areas, to whom Lut was sent. Allah the Exalted shook the earth beneath them and turned their area into a reeking lake, as stinking as the disbelief, tyranny and defiance of the Truth that they had,
Aikah means a dense bush; wood; forest; jungle, These people resided in such a place. Holy Prophet Shu'aib (علیہ السلام) was sent to this nation. They disobeyed him and were destroyed by Divine punishment.
People of Tubba'
Tubba' was the title of the king of Yemen. The necessary explanation has been given in volume seven in Surah Ad-Dukhan under [ 44:37].
Tazkirul Quran
Maulana Wahiduddin KhanOn ayahs 11–14
The meaningfulness of the universe, its creative wisdom, its being free of shortcomings, and its being consistent with human needs compel every thinking and rational man to accept the sublimity of creation, and one who gives serious consideration to the system of the universe, will find the Creator in His creations. He will see a glimpse of the other world (the Hereafter) in this world, because, in fact, the world of the Hereafter is essentially another, more superior form of the present world.
