Sahih Muslim 1527dBook 21, Hadith 46
وَحَدَّثَنِي حَرْمَلَةُ بْنُ يَحْيَى، حَدَّثَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، أَخْبَرَنِي سَالِمُ بْنُ عَبْدِ اللَّهِ، أَنَّ أَبَاهُ، قَالَ قَدْ رَأَيْتُ النَّاسَ فِي عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم إِذَا ابْتَاعُوا الطَّعَامَ جِزَافًا يُضْرَبُونَ فِي أَنْ يَبِيعُوهُ فِي مَكَانِهِمْ وَذَلِكَ حَتَّى يُئْوُوهُ إِلَى رِحَالِهِمْ . قَالَ ابْنُ شِهَابٍ وَحَدَّثَنِي عُبَيْدُ اللَّهِ بْنُ عَبْدِ اللَّهِ بْنِ عُمَرَ أَنَّ أَبَاهُ كَانَ يَشْتَرِي الطَّعَامَ جِزَافًا فَيَحْمِلُهُ إِلَى أَهْلِهِ .
I saw people being beaten during the lifetime of Allah's Messenger (ﷺ) in case they bought the foodgrain in bulk, and then sold them at that spot before taking it to their places. This hadith is narrated on the authority of 'Ubaidullah b. Abdullah b. 'Umar through another chain of transmitters (and the words are):" His father (Ibn 'Umar) used to buy foodgrains in bulk and then carried them to his people."
