The transfer of a salam contract before the due date

Question:
Honorable Shaykh, a person made a salam contract with another for a sum of one hundred thousand riyals, on the condition that the recipient of the money would deliver to him one hundred tons of wheat after one year. However, the recipient of the money did not plant due to certain circumstances. So he said to the owner of the right, before the due date arrived, “I will transfer you to a person from whom I will request that you take one hundred tons from him.” The owner of the right accepted, and the person to whom the transfer was made also accepted. What is the ruling on this?

Answer:
There is no harm. They transferred it to another regarding the grains that are in his liability, to be delivered to him.
