35. My father said with it that Sa`d ibn `Abd Allah said, on the authority of Ya`qub ibn Yazid, on the authority of Safwan ibn Yahya, on the authority of Salmah al-Hannat, that Abu `Abd Allah al-Sadiq said: Whenever there is food in a town other than what one person has bought then it is permissible for him to hold on to the excess of commodity. If there is sufficient food available for people in the city, then the price will not rise merely because one person purchases the excess. Verily, the price only rises if one person buys all the food that enters the city.
