Muwatta Malik 1344
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنْ سُلَيْمَانَ بْنِ يَسَارٍ، أَنَّهُ أَخْبَرَهُ أَنَّ عَبْدَ الرَّحْمَنِ بْنَ الأَسْوَدِ بْنِ عَبْدِ يَغُوثَ فَنِيَ عَلَفُ دَابَّتِهِ فَقَالَ لِغُلاَمِهِ خُذْ مِنْ حِنْطَةِ أَهْلِكَ طَعَامًا فَابْتَعْ بِهَا شَعِيرًا وَلاَ تَأْخُذْ إِلاَّ مِثْلَهُ .
Yahya related to me from Malik from Nafi that Sulayman ibn Yasar told him that one time the fodder of the animals of Abd ar-Rahman ibn al-Aswad ibn Abd Yaghuth was finished so he said to his slave, "Take some of your family's wheat as food and buy with it barley, and take only a like quantity.' "
