Hadith 1515 c - The Book of Transactions - Sahih Muslim - صحيح مسلم - Collection of Actions, Sayings and Teachings of Prophet Muhammad (صلى الله عليه و سلم) - Kutub as-Sittah

21. The Book of Transactions - كتاب البيوع

4) Chapter: The prohibition of urging a buyer to cancel a purchase in order to sell him one's own goods; And urging a seller to cancel a sale already agreed upon so that one can buy the goods oneself; And the prohibition of artificially inflating prices; And the prohibition of letting milk accumulate in the udder in order to deceive the purchaser

Abu Huraira reported Allah's Messenger (may peace'be upon him) as saying:

Do not go out to meet riders to enter into transaction with them; none of you must buy in opposition to another, nor must you bid against one another; a townsman must not sell for a man from the desert, and do not tie up udders of carnels and sheep, and he who buys them after that has been done has two courses open to him: after he has milked them he may keep them if he is pleased with them, or he may return them along with a sit of dates if he is displeased with them.

4) باب تَحْرِيمِ بَيْعِ الرَّجُلِ عَلَى بَيْعِ أَخِيهِ وَسَوْمِهِ عَلَى سَوْمِهِ وَتَحْرِيمِ النَّجْشِ وَتَحْرِيمِ التَّصْرِيَةِ

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏‏ ‏.‏ "‏ لاَ يُتَلَقَّى الرُّكْبَانُ لِبَيْعٍ وَلاَ يَبِعْ بَعْضُكُمْ عَلَى بَيْعِ بَعْضٍ وَلاَ تَنَاجَشُوا وَلاَ يَبِعْ حَاضِرٌ لِبَادٍ وَلاَ تُصَرُّوا الإِبِلَ وَالْغَنَمَ فَمَنِ ابْتَاعَهَا بَعْدَ ذَلِكَ فَهُوَ بِخَيْرِ النَّظَرَيْنِ بَعْدَ أَنْ يَحْلُبَهَا فَإِنْ رَضِيَهَا أَمْسَكَهَا وَإِنْ سَخِطَهَا رَدَّهَا وَصَاعًا مِنْ تَمْرٍ ‏"
