It is narrated from Sayyiduna Abu Huraira (may Allah be pleased with him) that a man said: O Messenger of Allah! Fix the prices. The Prophet (peace and blessings be upon him) said: It is only Allah Almighty who raises and lowers the prices. I hope to meet Allah Almighty in such a state that I have not wronged anyone. When another person also said the same thing, asking you to fix the prices, the Prophet (peace and blessings be upon him) said: Call upon Allah Almighty (and pray to Him).
