What is the ruling on buying a car in installments with a company’s lien clause, and is it permissible to sell it or benefit from its money despite the existence of this condition, and is the car considered a pledge?

The car is mortgaged to the company under what is called a "formal mortgage," which is permissible. This means that its sale is prohibited because it is mortgaged to the company. "Privilege" is a legal term that grants the company priority in collecting its debt documented by the mortgage. Therefore, the car cannot be sold except by expediting the company's right, because selling a mortgaged item without expediting the mortgagee's right deprives the company of its right to secure its assets.
