Let not your choosing of them be in accordance with your own discernment...
Let not your choosing of them be in accordance with your own discernment, confidence and good opinion, for men make themselves known to the discernment of rulers by dissimulating and serving them well, even though beyond this there may be nothing of sincere counsel and loyalty. Rather examine them in that with which they were entrusted by the righteous before you. Depend upon him who has left the fairest impression upon the common people and whose countenance is best known for trustworthiness.
This will be proof of your sincerity toward God and toward him whose affair has been entrusted to you. Appoint to the head of each of your concerns a chief from among these men, (a person) who is neither overpowered when these concerns are great nor disturbed when they are many. Whatever fault of your secretaries you overlook will come to be attached to you (4).
Then make merchants and craftsmen-those who are permanently fixed, those who move about with their wares and those who profit from (the labor of) their own body (7) -your own concern, and urge others to do so, for they are the bases of benefits and the means of attaining conveniences. They bring (benefits and conveniences) from remote and inaccessible places in the land, sea, plains and mountains, and from places where men neither gather together nor dare to go.
(The merchants and craftsmen) are a gentleness from which there is no fear of calamity and a pacifity from which there is no worry of disruption. (8) Examine their affairs in your presence and in every corner of your land. But know, nevertheless, that in many of them is shameful miserliness, detestable avarice, hoarding of benefits and arbitrariness in sales. This is a source of loss to all and a stain upon rulers.
So, prohibit hoarding (ihtikar), for the Messenger of God (may God bless him and his household) prohibited it. (9) Let selling be an openhanded selling, with justly balanced scales and prices which do not prejudice either party, buyer or seller. (10) As for him who lets himself be tempted to hoard after you have forbidden him (to do so), make an example of him and punish him, but not excessively.
(5) Then (fear) God, (fear) God regarding the lowest class, the wretched, needy, suffering and disabled who have no means at their disposal, for in this class there is he who begs and he who is needy (but does not beg). Be heedful for God’s sake of those rights of theirs which He has entrusted to you.
