Instructions for Hasan, when returning from Siffin
Nahj al-Balāgha|Volume 1|Book 2|Chapter 31
وَاجْعَلْ لِكُلِّ إِنْسَانٍ مِنْ خَدَمِكَ عَمَلًا تَأْخُذُهُ بِهِ، فَإِنَّهُ أَحْرَى أَلَّا يَتَوَاكَلُوا فِي خِدْمَتِكَ. وَأَكْرِمْ عَشيِرَتَكَ، فَإِنَّهُمْ جَنَاحُكَ الَّذِي بِهِ تَطِيرُ، وَأَصْلُكَ الَّذِي إِلَيْهِ تَصِيرُ، وَيَدُكَ الَّتِي بِهَا تَصُولُ.
For everyone among your servants fix a work for which you may hold him responsible. In this way, they will not fling the work one over the other. Respect your kinsmen because they are your wings with which you fly, the origin towards which you return and your hands with which you attack.
