Yahya related to me from Malik from Nafi that Abdullah ibn Umar said, "In the time of the Messenger of Allah, may Allah bless him and grant him peace, we used to buy food. He sent orders for us to move our purchases from the place in which we purchased them to another place before we re-sold them."
Muwatta Malik Book 31, Hadith 42
← Previous Hadith Yahya related to me from Malik from Abdullah ibn Dinar from Abdullah ibn Umar that the Messenger of Allah, may Allah bless him and grant him peace, said, "Someone who buys food, must not sell it until he takes possession of it."

Muwatta Malik Book 31, Hadith 41 Next Hadith → Yahya related to me from Malik from Nafi that Hakim ibn Hizam traded in food for people as Umar ibn al-Khattab had ordered him to do. Hakim re-sold the food before he had taken delivery of it. That reached Umar ibn al-Khattab and he revoked the sale and said, "Do not sell food which you have purchased until you take delivery of it."
