Sunan Abi Dawud, Hadith 3486 ⓘ

Narrated Ibn 'Umar: During the time of Messenger of Allah we used to buy grain, and he sent a man to us who ordered us to move it from the spot where we had bought it to some other place, before we sold it without weighing or measuring it.

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّهُ قَالَ كُنَّا فِي زَمَنِ رَسُولِ اللَّهِ صلى الله عليه وسلم نَبْتَاعُ الطَّعَامَ فَيَبْعَثُ عَلَيْنَا مَنْ يَأْمُرُنَا بِانْتِقَالِهِ مِنَ الْمَكَانِ الَّذِي ابْتَعْنَاهُ فِيهِ إِلَى مَكَانٍ سِوَاهُ قَبْلَ أَنْ نَبِيعَهُ - يَعْنِي - جُزَافًا ‏.‏
