Mishkat al-Masabih 11 Business Transactions كتاب البيوع 82

وَعَنِ ابْنِ عُمَرَ قَالَ: كَانُوا يَبْتَاعُونَ الطَّعَامَ فِي أَعلَى السُّوقِ فيبيعُونَه فِي مكانهِ فَنَهَاهُمْ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ بَيْعِهِ فِي مَكَانِهِ حَتَّى يَنْقِلُوهُ. رَوَاهُ أَبُو دَاوُد وَلم أَجِدهُ فِي الصَّحِيحَيْنِ

Ibn ‘Umar said they used to buy grain in the upper part of the market and sell it in the same spot, but God’s Messenger forbade them to sell it there before removing it. Abu Dawud transmitted it. I have not found it in the two Sahihs .
