Is it permissible to clad the facade of a house with marble, ceramic, or Hallan stone?

Allah has forbidden wasting money through extravagance or squandering, and moderation in spending is obligatory. There is no fixed limit that defines extravagance or stinginess; rather, it varies according to the person's situation, time, and place. Covering the facade of a house with marble has a ruling that differs according to people's circumstances: it is permissible for a wealthy person who has ample means, as long as it is not considered extravagance for them. It is considered extravagance for a person of moderate means, and as for the poor, their doing so is foolish. A rich person may need a broader scope in spending that differs from others, as Allah Almighty says: (Let a man of wealth spend from his wealth, and he whose provision is restricted - let him spend from what Allah has given him. Allah does not burden a soul beyond what He has given it. Allah will bring about ease after hardship). This is constrained by His saying: (And do not be extravagant. Indeed, He does not like those who are extravagant).
