Anas (may Allah be pleased with him) narrates that once, during the time of the Messenger of Allah (peace and blessings be upon him), the prices (of grain and other goods) increased. So the people said: "O Messenger of Allah! Fix prices for us." He replied: "The One who fixes prices is Allah alone. He is the One who restricts provision, expands it, opens it, and grants abundant sustenance. I wish to meet my Lord in such a state that none of you demands from me compensation for any injustice regarding life or wealth." Imam Tirmidhi says:
This hadith is Hasan Sahih.
