٣- عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ وَأَحْمَدَ بْنِ مُحَمَّدٍ عَنِ الْحَسَنِ بْنِ مَحْبُوبٍ عَنْ زَيْدٍ الشَّحَّامِ قَالَ سَأَلْتُ أَبَا عَبْدِ اللهِ (عَلَيْهِ السَّلام) عَنْ رَجُلٍ يَشْتَرِي سِهَامَ الْقَصَّابِينَ مِنْ قَبْلِ أَنْ يَخْرُجَ السَّهْمُ فَقَالَ لا يَشْتَرِي شَيْئاً حَتَّى يَعْلَمَ مِنْ أَيْنَ يَخْرُجُ السَّهْمُ فَإِنِ اشْتَرَى شَيْئاً فَهُوَ بِالْخِيَارِ إِذَا خَرَجَ. 
3. A number of our people have narrated from Sahl ibn Ziyad and Ahmad ibn Muhammad from al-Hassan ibn Mahbub from Zayd al- Shahham who has said the following: “This is concerning my question before abu ‘Abd Allah , about the case of a man who bought the shares of butchers before the shares were taken out. He (the Imam) said, ‘Nothing can be purchased until it is known where the shares come. If he buys like this he has the choice to buy or not to buy it.’”
