Muwatta' Malik 31-

Translation

Yahya related to me from Malik from Abdullah ibn Dinar from Abdullah ibn Umar that a man mentioned to the Messenger of Allah ﷺ that he was always being cheated in business transactions. The Messenger of Allah ﷺ said, "When you enter a transaction, say, 'No trickery.' So whenever that man entered a transaction, he would say, 'No trickery.' "
