Narated By AbuBakr ibn AbdurRahman ibn al-Harith ibn Hisham : The Prophet (pbuh) said: If a man sells (his) property and the man who buys it becomes insolvent, and the seller does not receive the price of the property he had sold, but finds his very property with him (i.e. the buyer), he is more entitled to it (than others). If the buyer dies, then the owner of the property is equal to the creditors.
