3- أَبُو عَلِيٍّ الأشْعَرِيُّ عَنْ مُحَمَّدِ بْنِ عَبْدِ الْجَبَّارِ عَنْ صَفْوَانَ عَنِ ابْنِ مُسْكَانَ عَنِ الْحَلَبِيِّ عَنْ أَبِي عَبْدِ اللهِ قَالَ كَانَ أَمِيرُ الْمُؤْمِنِينَ (عَلَيْهِ السَّلام) يَكْتُبُ إِلَى عُمَّالِهِ لا تُسَخِّرُوا الْمُسْلِمِينَ وَمَنْ سَأَلَكُمْ غَيْرَ الْفَرِيضَةِ فَقَدِ اعْتَدَى فَلا تُعْطُوهُ وَكَانَ يَكْتُبُ يُوصِي بِالْفَلاحِينَ خَيْراً وَهُمُ الأكَّارُونَ.
3. Abu Ali al-Ash’ariy has narrated from Muhammad ibn ‘Abd al-Jabbar from Safwan from ibn Muskan from al-Halabiy who has said the following: “Abu ‘Abd Allah 
, has said that ’Amir al-Mu’minin, would write to his agents, ‘You must not make Muslims to perform free labor. Whoever of you asks for what is not obligatory, he has committed transgression and you must not give him anything.’ He (‘Amir al-Mu’minin) would write and recommend about farmers good advice, about them and laborers on hire.’”
