وَ رَوَى عُبَيْدُ اَللَّهِ بْنُ عَلِيٍّ اَلْحَلَبِيُّ وَ مُحَمَّدٌ اَلْحَلَبِيُّ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ: قُدِّمَ لِأَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ مَتَاعٌ مِنْ مِصْرٍ فَصَنَعَ طَعَاماً وَ دَعَا لَهُ اَلتُّجَّارَ فَقَالُوا نَأْخُذُهُ بِدَهْ دَوَازْدَهْ فَقَالَ "وَ كَمْ يَكُونُ ذَلِكَ" فَقَالُوا فِي كُلِّ عَشَرَةِ آلاَفٍ أَلْفَيْنِ قَالَ "فَإِنِّي أَبِيعُكُمْ هَذَا اَلْمَتَاعَ بِاِثْنَيْ عَشَرَ أَلْفاً".
Ubaydullah ibn Ali al-Halabi and Muhammad al-Halabi narrated from Abu Abdullah عليه السلام: Goods arrived for Abu Abdullah عليه السلام from Egypt. Imam عليه السلام prepared food and invited the merchants. They said: "We will take it at dah dawazdah (a price of twelve)." Imam عليه السلام asked: "And how much does that amount to?" They replied: "For every ten thousand, two thousand more." Imam عليه السلام said: "Then I will sell you these goods for twelve thousand."
