Hadith.3969 - It was said to the Prophet, peace and blessings be upon him and his family: "Would you set a fixed price for us, for prices rise and fall?" The Prophet (sw) replied: "I would not meet Allah (swt), the Exalted, with an innovation about which He (swt) has revealed nothing to me. So leave the servants of Allah (swt) to benefit from one another. And if you are consulted for advice, then give sincere advice."
