These are the orders issued by the creature of Allah, Ali, the son Abu Taalib (a) to Maalik, the son of Ashtar when he appointed Maalik as the Governor of Egypt to collect Zakat there, to combat the enemies of Islam and Egypt, to work for the welfare of its people and to look after its prosperity.
- Do not feel ashamed to forgive and forget.
- Do not hurry over punishments and do not be pleased and do not be proud of your power to punish.
- Do not get angry and lose your temper quickly over the mistakes and failures of those over whom you rule. On the contrary, be patient and sympathetic with them.
- Anger and desire of vengeance are not going to be of much help to you in your administration.
- Never say to yourself, "I am their Lord, their ruler and all in all over them and that I must be obeyed submissively and humbly" because such a thought will unbalance your mind, will make you vain and arrogant, will weaken your faith in religion and will make you seek support of any power other than that of Allah.
- If you ever feel any pride or vanity on account of your sway and rule over your subjects then think of the supreme sway and rule of the Lord over the Universe, the extent of His creations, the supremacy of His Might and Glory, His Power to do things which you cannot even dream of doing and His control over you which is more dominating than that which you can ever achieve over anything around you. Such thoughts will cure your mental weakness, will keep you away from vanity and rebellion (against Allah), will reduce your arrogance and haughtiness and will take you back to the sanity which you had foolishly deserted... Try carefully to realize that a ruler can create goodwill in the minds of his subjects and can make them faithful and sincere to him only when he is kind and considerate to them, when he reduces their troubles, when he does not oppress them and when he never asks for things which are beyond their power. These are the principles which you should keep in mind and act upon".
- Awaken your heart to kindness and mercy for the people and love and tenderness for them. Never, never act with them like a predatory beast which seeks to be satiated by devouring them, for the people fall into two categories: they are either your brethren in faith or your kindred in creation ... Do not ever say, 'I have been given authority' or 'My command should be obeyed.' Because it corrupts the heart, consumes one's faith, and invites calamities.

- *** Husayn al-Nuri al-Tabarsi, Mustadrak al-Wasā'il, vol.11, p.323.
- Allah, the Exalted, gave the angels intellect without desires, He gave the animals desires without intellect, and He gave both to the sons of Adam. So a man whose intellect prevails over his desires is better than the angels, whilst a man whose desire prevails over his intellect is worse than the animals.
