عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ هَارُونَ بْنِ مُسْلِمٍ عَنْ مَسْعَدَةَ بْنِ صَدَقَةَ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) أَنَّ أَمِيرَ الْمُؤْمِنِينَ ( عليه السلام ) كَانَ يَرْكَبُ بَغْلَةَ رَسُولِ اللَّهِ ( صلى الله عليه وآله ) ثُمَّ يَمُرُّ بِسُوقِ الْحِيتَانِ فَيَقُولُ أَلَا لَا تَأْكُلُوا وَ لَا تَبِيعُوا مَا لَمْ يَكُنْ لَهُ قِشْرٌ .
9. Ali ibn Ibrahim has narrated [from his father] from Harun ibn Muslim from Mas’adah ibn Sadaqah who has said the following: “Abu ‘Abd Allah , has stated this Hadith. ’Amir al-Mu’minin would ride the mule of the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause. He (the Imam) then would pass by the fish market and say, ‘You must not use for food and must not sell whatever does not have scales.’”
