Praise be to Allaah.
The company does not have the right to sell furniture or
other movable items until after the transaction has been completed and the
sold item has been moved to their property and has been transferred from the
possession of the seller to another place, then the transaction is completed
As for paying a deposit to the company before that, it is not permissible and they do not have the right to sell anything until after they have taken possession of it and moved it from the seller's place to another place. And Allaah is the source of strength. End quote.
