A man bought a piece of land and paid the deposit but did not take possession of it. Is it permissible for him to sell it and then pay the remaining amount to the original seller?

Question:
Honorable Shaykh, may Allah grant you success. The questioner says: I have a real estate office. I have a real estate office, and I bought a piece of land and paid the deposit to the seller. But the full amount was not paid, and the title was not transferred to my name. He says: A customer came to me and said, "I want this land." His question is: Is it permissible for me to sell it to him? Then I will direct him to the original seller, and I will take the difference.

Answer:
No. You do not sell it while you have not completed ownership of it. Unless you have completed acquiring it, do not sell it until you have completed acquiring it. Yes, as long as it is not completed, it is not your property. Yes.
