It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that a man presented himself in the court of the Prophet and said, "O Messenger of Allah (peace and blessings be upon him), fix the prices of things." The Noble Prophet (peace and blessings be upon him) said, "It is Allah who makes prices high and low, and I wish to meet Allah in such a state that there is no injustice from my side to anyone."
