Chapter on Sales

It is narrated from Khalid ibn Hajjaj Al-Karkhi, who said: I asked Abu Abdillah عليه السلام: "I buy food on deferred payment until a specified time, and then merchants request to buy it from me before I take possession of it." Imam عليه السلام said: "There is no harm in selling it on deferred payment, as you purchased it, but you are not allowed to hand it over or take possession of it before you actually receive it." I asked: "Once I take possession of it, may I be your ransom, can I then hand it over using its measured amount?" Imam عليه السلام said: "There is no harm in that if they are satisfied with it." Imam عليه السلام also said: "Any food you purchase from a field (baydar) or a district (tassuj), and then Allah سبحانه وتعالى causes it to perish, the buyer is only entitled to his principal amount. But if he purchases food with a general description and does not specify a village or location, then the seller is obligated to deliver it." I further asked Abu Abdillah عليه السلام: "I buy food from a man and then sell it to another man before measuring it, saying to him, 'Send your agent to witness its measurement when I take possession of it.'" Imam عليه السلام said: "There is no harm in that."
