Hadith 776عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ عَبْدِ اللَّهِ بْنِ الْمُغِيرَةِ عَنْ عَبْدِ اللَّهِ بْنِ سِنَانٍ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ كَانَ أَمِيرُ الْمُؤْمِنِينَ عَلِيُّ بْنُ أَبِي طَالِبٍ ( عليه السلام ) بِالْكُوفَةِ يَرْكَبُ بَغْلَةَ رَسُولِ اللَّهِ ( صلى الله عليه وآله ) ثُمَّ يَمُرُّ بِسُوقِ الْحِيتَانِ فَيَقُولُ لَا تَأْكُلُوا وَ لَا تَبِيعُوا مِنَ السَّمَكِ مَا لَمْ يَكُنْ لَهُ قِشْرٌ .
6. Ali ibn Ibrahim has narrated from his father from ‘Abd Allah ibn al-Mughirah from ‘Abd Allah ibn Sinan who has said the following: “Abu ‘Abd Allah (a.s.), has stated this Hadith. ’Amir al-Mu’minin, Ali Ibn Abu Talib in al-Kufah would ride the mule of the Messenger of Allah (saww) then pass by the fish market and say, ‘Do not use for food and do not sell of fish whatever has no scales.’”
