ومن كتاب له (عليه السلام) إلى كميل بن زياد النخعي وهو عامله على هيت ينكر عليه تركه دفع من يجتاز به من جيش العدو طالبا الغارة

To Kumayl ibn Ziyād an-Nakha‘ī, the Governor of Hit expressing displeasure on his inability to prevent the the enemy forces that passed through his area from marauding.

أَمَّا بَعْدُ، فَإِنَّ تَضْيِيعَ الْمَرْءِ مَا وُلِّيَ، وَتَكَلُّفَهُ مَا كُفِيَ، لَعَجْزٌ حَاضِرٌ، وَرَأْيٌ مُتَبَّرٌ، وَإِنَّ تَعَاطِيَكَ الْغَارَةَ عَلَى أَهْلِ قِرْقِيسِيَا، وَتَعْطِيلَكَ مَسَالِحَكَ الَّتِي وَلَّيْنَاكَ ـ لَيْسَ بِهَا مَنْ يَمْنعُهَا، وَلَا يَرُدُّ الْجَيْشَ عَنْهَا ـ لَرَأْيٌ شَعَاعٌ. فَقَدْ صِرْتَ جِسرْاً لِمَنْ أَرَادَ الْغَارَةَ مِنْ أَعْدَائِكَ عَلَى أَوْلِيَائِكَ، غَيْرَ شَدِيدِ الْمَنْكِبِ، وَلَا مَهِيبِ الْجَانِبِ، وَلَا سَادٍّ ثُغْرَةً، وَلَا كَاسِرٍ لِعَدُوٍّ شَوْكَةً، وَلَا مُغْنٍ عَنْ أَهْلِ مِصْرِهِ، وَلَا مُجْز عَنْ أَميِرِهِ.

Now, the neglecting by a man of what he has been made responsible for and doing what is to be done by others is a manifest weakness and a ruinous sight. Certainly, your advance on the people of Qarqīsiyā, and your leaving the arsenals over which we had set you, without anyone to protect them or to repulse the enemy force, savoured of shattered thinking. In this way, you served like a bridge for the enemy who came marauding on your allies while your arms were weak, you had no awe around you; you could not prevent the enemy from advancing; you could not break his might; you could not defend the people of your area and you could not discharge functions on behalf of your Imām.
