Arabic (Original)
حَدَّثَنَا رَوْحُ بْنُ عُبَادَةَ قَالَ حَدَّثَنَا شُعْبَةُ قَالَ حَدَّثَنَا سَيَّارٌ عَنِ الشَّعْبِيِّ عَنْ أَبِي هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ لَا تَبَايَعُوا بِالْحَصَاةِ وَلَا تَنَاجَشُوا وَلَا تَبَايَعُوا بِالْمُلَامَسَةِ وَمَنْ اشْتَرَى مِنْكُمْ مُحَفَّلَةً فَكَرِهَهَا فَلْيَرُدَّهَا وَلْيَرُدَّ مَعَهَا صَاعًا مِنْ طَعَامٍ.
English Translation
Rawh ibn Ubadah narrated to us, he said: Shu'bah narrated to us, he said: Sayyar narrated to us, from al-Sha'bi, from Abu Hurayrah, that the Messenger of Allah, peace and blessings be upon him, said: "Do not trade by throwing pebbles, and do not engage in artificial bidding (najash), and do not trade by touching alone; and whoever among you buys an animal whose udder has been left unmilked to appear plentiful and dislikes it, let him return it, and return along with it a sa' of food."
