Two transactions in one

Q: What is the ruling on selling a car for 10,000 if in cash or 12,000 if in installments as is the case in car exhibitions today?

A: If someone sells a car or anything else to another person in return for 10,000 riyals in cash or 12,000 riyals in installments and they go out without determining any of those two options, then this sale will be invalid because of not determining the status of this sale. Scholars have cited the prohibition of the Prophet (peace be upon him) on making two transactions in one bargain for that effect. This Hadith was reported by Ahmad, Al-Nasa'y and Al-Tirmidhy. Al-Tirmidhy regarded this Hadith as an authentic one. If the seller and the buyer agree on the way of payment whether in cash or in installments during the time of signing the contract and before leaving, then this sale will be valid. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
