It is narrated from Sayyiduna Abu Juhayfah (may Allah be pleased with him) that the people said: O Messenger of Allah, fix prices for us. He (peace and blessings be upon him) said: "It is Allah who fixes prices; He is the One who withholds and the One who grants in abundance. I hope to meet Allah in a state where none of you is demanding from me redress for any wrong concerning honour or wealth."
