و درود خدا بر او فرمود: عهد و پیمانها را پاسدارید بخصوص با وفاداران. Amir al-Mu'minin, peace be upon him, said: Adhere to contracts and entrust fulfilment to steadfast persons.

وَ قَالَ (عليه السلام): اعْتَصِمُوا بِالذِّمَمِ فِي أَوْتَادِهَا

Amir al-Mu'minin, peace be upon him, said: Adhere to contracts and entrust fulfilment to steadfast persons.
