What is the description of the legitimate dwelling that the husband provides for his wife, and is it an apartment or a palace, and what did the four imams of fiqh say about that?

The legitimate dwelling that a husband must provide for his wife is clarified in Allah’s saying: "Lodge them where you dwell, according to your means" (Surat At-Talaq: 6). Its description depends on custom, the husband's financial circumstances, and the wife's situation.
