As salamo alaikum.
Is it jayaz to buy a vehicle or any thing in installment.While paying the installment,we need to pay interest also,so is it jayaz or not?
Ref. No 939
In the name of Allah the most Gracious the most Merciful
The answer to your question is as follows:
Dealing with riba/interest (without a severe need or a valid reason that is acceptable in Islam) is a major sin in Islam and the Quran says it is Haram. A person should abstain from it throughout his life.
