Sayyiduna Anas bin Malik (may Allah be pleased with him) narrated that some people came to the Prophet (peace and blessings be upon him) and said: O Messenger of Allah, fix prices for us. the Messenger of Allah (peace and blessings be upon him) said: "The dearness and cheapness of your goods are in the Hand of Allah, the Mighty and Majestic. I hope to meet Allah, the Mighty and Majestic, in a state where none of you has any claim against me for a wrong concerning property or blood."
