And, he is asked to support Allah (by supporting the right) with his heart, hand and tongue because Allah has promised to support whoever supports Him and glorify whoever glorifies Him. He is ordered to control his soul’s fancies and to subdue his soul if it wants to err because the soul often incites towards evil except those whom Allah has mercy upon. O Malik, know that I have sent you to a country that had experienced just and unjust rulers before you.
The people will think of your deeds as you thought of the deeds of the Walis who preceded you, and they will talk about you as you talked about the Walis that ruled before you. The virtuous men will be known by what is said about them by the people (by the favor of Allah). Let the loveliest provision to your self be the benevolent doing. Control your fancy and prevent yourself from what is not legal to you because controlling one’s self is the very fairness to it in what it likes or dislikes.
Fill your heart with mercy, love and kindness towards your people and do not be with them like a beast, waiting for an opportunity to eat them because people are of two kinds - either a brother to you in religion or an equal to you in humanity. They fall into mistakes and may be incited by the slips. They may commit sins on purpose or unknowingly. So you are to forgive them as you like Allah to forgive you.
You rule over them and the responsible guardian rules over you and Allah is the Ruler upon the one, who appointed you. Allah tries you by managing your people’s affairs, so do not be in a war against Allah (by trespassing His Sharia and by wronging His people) because you are unable to put up with His wrath and you cannot do without his forgiveness and mercy. Do not regret when you forgive someone and do not boast when you punish someone.
Do not be angry about something that you may find an excuse for it. Do not say: ‘I am the superior. I order and I must be obeyed’ for it corrupts the heart, destroys the religion, and approaches to the others (the opponents). If your high position gives a sense of splendor or pride, you are to think of the supreme power of Allah over you and His ability to act upon you what you can never put up with.
This will lessen your vanity, prevent your sharpness and restore what is missed by your reason for you. Beware not to compare yourself with Allah in His greatness or to imitate Him in His supreme power, because Allah degrades every arrogant and demeans every haughty one.
