"I saw people being beaten (in punishment) at the time of the Messenger of Allah for buying food unmeasured and selling it before bringing it to their own camp." (Using translation from Nasāʾī 4608)
عَنْ أَبِيهِ أَنَّهُمْ كَانُوا يُضْرَبُونَ عَلَى عَهْدِ رَسُولِ اللهِ ﷺ إِذَا اشْتَرَوْا طَعَامًا جُزَافًا أَنْ يَبِيعُوهُ فِي مَكَانِهِ حَتَّى يُؤْوُوهُ إِلَى رِحَالِهِمْ
