Muwatta Malik 1331

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّهُ قَالَ كُنَّا فِي زَمَانِ رَسُولِ اللَّهِ صلى الله عليه وسلم نَبْتَاعُ الطَّعَامَ فَيَبْعَثُ عَلَيْنَا مَنْ يَأْمُرُنَا بِانْتِقَالِهِ مِنَ الْمَكَانِ الَّذِي ابْتَعْنَاهُ فِيهِ إِلَى مَكَانٍ سِوَاهُ قَبْلَ أَنْ نَبِيعَهُ ‏.‏

Yahya related to me from Malik from Nafi that Abdullah ibn Umar said, "In the time of the Messenger of Allah, may Allah bless him and grant him peace, we used to buy food. He sent orders for us to move our purchases from the place in which we purchased them to another place before we re-sold them
