It is narrated from Sayyiduna Anas (may Allah be pleased with him) that in the time of the Messenger of Allah (peace and blessings be upon him) there was a man who used to trade, but there was some weakness in his intellect and understanding. So his family came to the Prophet (peace and blessings be upon him) and said: "O Messenger of Allah, place a restriction (on his financial dealings) upon so-and-so, for he buys and sells while there is weakness in his understanding." So the Prophet (peace and blessings be upon him) called him and forbade him from trading. He said: "O Prophet of Allah, I cannot do without buying and selling." Thereupon the Messenger of Allah (peace and blessings be upon him) said: "If you are not going to give up trading, then say (when making a deal): 'Ha', fa la khilabah' (Here you are (take the price), and (remember that in this sale) there is to be no deception)."
