حَدَّثَنَا يَحْيَى عَنْ التَّيْمِيِّ عَنْ أَبِي عُثْمَانَ عَنْ ابْنِ مَسْعُودٍ مَنْ اشْتَرَى مُحَفَّلَةً وَرُبَّمَا قَالَ شَاةً مُحَفَّلَةً فَلْيَرُدَّهَا وَلْيَرُدَّ مَعَهَا صَاعًا وَنَهَى النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ تَلَقِّي الْبُيُوعِ
مسند امام احمد بن حنبل · Hadith 4096
It was narrated from Ibn Mas'ood: Whoever buys an animal that has been left unmilked - or perhaps he said: a ewe that has been left unmilked - let him return it and return a sa with it. And the Prophet (PBUH) forbade intercepting people with their goods (before they reached the market).
