Hakeem bin Hizam reported,

The Messenger of Allah ﷺ said, "The buyer and seller each have the option to cancel the sale as long as they have not parted. If they are truthful and disclose any defects, their transaction will be blessed for them, but if they conceal and lie, the blessing of their transaction will be wiped out."
