This is why Allah refuted their doubts;
وَكَمْ أَهْلَكْنَا قَبْلَهُم مِّن قَرْنٍ
And how many a generations have We destroyed before them!
This means, "How many nations and generations did We destroy of those who denied (this message) due to their disbelief."
...
هُمْ أَحْسَنُ أَثَاثًا وَرِيْيًا
who were better in wealth, goods and outward appearance.
This means that they were better than these present people in wealth, possessions, looks and appearance.
Al-A`mash reported from Abu Zibyan, who reported from Ibn Abbas that he said concerning the Ayah,
خَيْرٌ مَّقَامًا وَأَحْسَنُ نَدِيًّا
(best dwellings and finest Nadiyyan),
"Position (Maqam) means home,
Nadi means place of gathering,
wealth refers to material possessions and
outward appearance is how they look physically."
Al-Awfi said that Ibn Abbas said,
"Position (Maqam) means dwelling,
Nadi means place of gathering and the blessing and happiness that they were living in.
This is as Allah says about the people of Fir`awn when He destroyed them and related the story of their situation in the Qur'an,
كَمْ تَرَكُواْ مِن جَنَّـتٍ وَعُيُونٍ
وَزُرُوعٍ وَمَقَامٍ كَرِيمٍ
How many gardens and springs that they (Fir`awn's people) left behind, and green crops and honored places (Maqam). (44;25-26)
Therefore,
position (Maqam) refers to their dwellings and splendid bounties, and
Nadi is the places of gathering and meeting where they used to congregate.
Allah said while relating the story to His Messenger of what happened with the people of Lut,
وَتَأْتُونَ فِى نَادِيكُمُ الْمُنْكَرَ
And practice Al-Munkar (evil deeds) in your meeting places (Nadiyakum). (29;29)
The Arabs call a place of gathering a Nadi."
