Arabic (Original)
حَدَّثَنَا مُحَمَّدُ بْنُ إِدْرِيسَ أَخْبَرَنَا مَالِكٌ عَنْ أَبِي الزِّنَادِ عَنْ الْأَعْرَجِ عَنْ أَبِي هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ لَا يَبِعْ بَعْضُكُمْ عَلَى بَيْعِ بَعْضٍ وَلَا يَبِعْ حَاضِرٌ لِبَادٍ وَلَا تَنَاجَشُوا وَلَا تَلَقَّوْا السِّلَعَ وَقَالَ مَطْلُ الْغَنِيِّ ظُلْمٌ وَإِذَا أُتْبِعَ أَحَدُكُمْ عَلَى مَلِيءٍ فَلْيَتْبَعْ.
English Translation
Abu Hurayrah narrated that the Messenger of Allah (peace be upon him) said: "None of you should sell over the sale of another. A city dweller should not sell on behalf of a desert dweller. Do not artificially inflate prices. Do not intercept goods before they reach the market." He also said: "The delay of a wealthy person (in paying his debt) is an injustice, and if any of you is referred to a solvent person (for payment), he should accept the referral."
