Book 35: Sales in which a Price is paid for Goods to be Delivered Later (As-Salam) · Hadith 3
Hadith text
Narrated Ibn `Abbas:The Prophet (ﷺ) came to Medina and the people used to pay in advance the price of dates to be delivered within two or three years. He said (to them), "Whoever pays in advance the price of a thing to be delivered later should pay it for a specified measure at specified weight for a specified period
Ibn Abbas (رضی اللہ عنہما) bataate hain: Nabi Madina aaye aur log khajoor ki qeemat pehle se ada karte the jinhe do ya teen saal ke baad delivery honi hoti. Aap ne (unse) kaha: "Jo koi kisi cheez ki qeemat pehle deta hai jise baad mein delivery hona hai, use muqarrar naap, muqarrar wazan, aur muqarrar muddat ke liye dena chahiye."
