Abdullah bin Dinar narrated that he heard Ibn 'Umar (RA) saying: A man mentioned to the Messenger of Allah ( صلی اللہ علیہ وسلم ) that he was deceived in a business transaction, whereupon Allah's Messenger ( صلی اللہ علیہ وسلم ) said: When you enter into a transaction, say: There should be no attempt to deceive.

This hadith has been narrated on the authority of 'Abdullah bin Dinar with the same chain of transmitters but these words are not found in it." When he buys he should say: There should be no attempt to deceive."This hadith has been narrated on the authority of 'Abdullah bin Dinar with the same chain of transmitters but these words are not found in it."
