أخبرنا محمد بن عبد الله بن المبارك، قال أنبأنا وكيع، قال حدثنا سفيان، عن عمرو بن دينار، قال سمعت ابن عمر، يقول كنا نخابر ولا نرى بذلك بأسا حتى زعم رافع بن خديج أن رسول الله صلى الله عليه وسلم نهى عن المخابرة‏.‏‏
 It was narrated that 'Amr bin Dinar said:                      "I heard Ibn 'Umar say: 'We used to sell grain before it was ripe and before it was evident that it was free of disease and blight (by means of Al-Mukhabarah). We did not see anything wrong with that, until Rafi' bin Khadij said that the Messenger of Allah had forbidden Al-Mukhabarah.'"
