Prohibition of Malpractices in Commerce

Ibn 'Umar (May Allah be pleased with them) said:
The Messenger of Allah ﷺ said, "Do not meet the merchandise till they arrive in the market."

[Al-Bukhari and Muslim].

وعن ابن عمر قال: قال رسول الله ﷺ :”لا تتلقوا السلع حتى يهبط بها إلى الأسواق" ((متفق عليه)).

Ibn 'Abbas (May Allah be pleased with them) said:
The Messenger of Allah ﷺ said, "The caravans carrying merchandise should not be met on the way to purchase from them; a man in the city should not sell for a man of the desert."

Tawus asked him (Ibn 'Abbas): "What do these words really imply?" He said: "He should not work as an agent on his behalf."

[Al-Bukhari and Muslim].

وعن ابن عباس رضي الله عنهما قال: قال رسول الله ﷺ : “لا تتلقوا الركبان، ولا يبع حاضر لباد" فقال له طاوس: ما قوله: لا بيع حاضر لباد؟ قال: لا يكون له سمسارًا. ((متفق عليه)).

Abu Hurairah (May Allah be pleased with him) said:
The Messenger of Allah ﷺ forbade that a man in the city should be the commission agent of a man from the desert and prohibited the practice of Najsh (i.e., offering a high price for something in order to allure another customer who is interested in the thing), and that a man should make an offer while the offer of his brother is pending; or that he should make a proposal of marriage while that of his brother is pending; or that a woman should try that a sister of hers might be divorced so that she might take her place.

Another narration is: The Messenger of Allah ﷺ forbade the people from meeting the caravan on the way for entering into business transaction with them; and the selling of the goods by a dweller of the city on behalf of a man of the desert; and the seeking by a woman the divorce of her sister (from her husband), and the practice of Najsh and leaving the animals unmilked (for sometime for the purpose of accumulation of milk to deceive the buyer).

[Al-Bukhari and Muslim].

وعن أبي هريرة رضي الله عنه قال: نهى رسول الله ﷺ أن يبيع حاضر لباد، ولا تناجشوا ولا يبيع الرجل على بيع أخيه، ولا يخطب على خطبة أخيه، ولا تسأل المرأة طلاق أختها لتكفأ ما في إنائها. وفي رواية قال: نهى رسول الله ﷺ عن التلقي وأن يبتاع المهاجر للأعرابي، وأن تشترط المرأة طلاق أختها، وأن يستام الرجل على سوم أخيه، ونهى عن النجش والتصرية" ((متفق عليه)).

Ibn 'Umar (May Allah be pleased with them) said:
The Messenger of Allah ﷺ said, "A person should not enter into a transaction when his (Muslim) brother has already negotiated, nor should he make a proposal of marriage when that of his brother is pending, except with the permission of the latter."

[Al-Bukhari and Muslim].

وعن ابن عمر رضي الله عنهما، أن رسول الله ﷺ قال: "لا يبع بعضكم على بيع بعض، ولا يخطب على خطبة أخيه إلا أن يأذن له" ((متفق عليه، وهذا لفظ مسلم))

'Uqbah bin 'Amir (May Allah be pleased with him) said:
The Messenger of Allah ﷺ said, "A Mu'min is the brother of another Mu'min; and thus it is not permissible for a Mu'min to make an offer while the offer of his brother is pending, nor should he make a proposal of marriage while that of his brother is pending till he withdraws his proposal."

[Muslim].

وعن عقبة بن عامر أن رسول الله ﷺ قال: "المؤمن أخو المؤمن، فلا يحل لمؤمن أن يبتاع على بيع أخيه ولا يخطب على خطبة أخيه حتى يذر" ((رواه مسلم)).
