أخبرني أبو الحسين محمد بن هارون الزنجاني، قال: حدثنا علي بن عبد العزيز، عن أبي عبيد القاسم بن سلام بأسانيد متصلة إلى النبي صلى الله عليه وآله في أخبار متفرقة أنه نهى عن المحاقلة والمزابنة، فالمحاقلة بيع الزرع وهو في سنبله بالبر وهو مأخوذ من الحقل، والحقل هو الذي تسميه أهل العراق: " القراح " ويقال في مثل: " لا تنبت البقلة الا الحقلة " والمزابنة بيع التمر في رؤوس النخل بالتمر، ورخص النبي صلى الله عليه وآله في العرايا واحدها عرية وهي النخلة يعريها صاحبها رجلا محتاجا، والاعراء أن يجعل له ثمرة عامها يقول: رخص لرب النخل أن يبتاع من تلك النخلة من المعرا بتمر لموضع حاجته، قال: وكان النبي صلى الله عليه وآله إذا بعث الخراص قال: خففوا في الخرص فإن في المال العرية والوصية.
1.	We were told by Abu’l-Hussain, Muhammed bin Harun al-Zanjani, that he said: I was told by Ali bin Abdul-Aziz, from Abu Ubaid, Qasem bin Salam, with connected chains of narrators (reaching) to the Prophet, Allah’s blessings be upon him and his Family, in scattered reports that he forbade muhaqala and muzabana. Muhaqala is to tell cultivation while it is in its spike in the wild. It stems from haql. Haql is what the people of Iraq call qurah. It is said, in a proverb: «A leguminous plant does not vegetate except a haqla.» Muzabana is to sell dates that are on the top of palm trees, with dates. The Prophet, Allah’s blessings be upon him and his Family, licensed with regards to ‘araya, whose singular form is ‘ariya, and it is a palm tree whose owner strips it in accordance to his need. The stripping (of palm trees) is that one permits its fruit for a year. He says: «He licensed for the owner of the palm tree that he sells, from that palm tree, what has been stripped, with dates, in accordance to his need. He said: When the Prophet, Allah’s blessings be upon him and his Family, used to send the estimator, he said: Take it lightly with estimation, for indeed, in the property lies what is stripped and what is to be bequeathed.
