The Chachnāma (Fatḥnāma-yi Sind) 31.2.5

31.2.5

Do not disappoint those who want estates and lands, but comply with their requests. Encourage them by giving them written promises of protection and safety. You must know that there are four ways of acquiring a kingdom—1stly, courtesy, conciliation, gentleness, and alliances; 2ndly, expenditure of money, and generous gifts; 3rdly, adoption of the most reasonable and expedient measures at the time of disagreement or opposition; and 4thly, the use of overawing force, power, strength and majesty in checking and expelling the enemy. Try to grant every request made by the princes and please them by giving them solemn promises. When they submit and settle a tribute upon themselves, receive from them whatever they bring for the treasury, whether money in coins or any shining metal; and show them favour in every way. If you want to send an envoy to the enemy, first test his wisdom, faith, intelligence and honesty; and let not Islám suffer from his going or speaking. Protect yourself from and guard against the misfortunes (arising) from the stratagems and plots and arts of the enemy; and be very cautious and careful in the disposal of important affairs. Be careful, when Déhar sends a confidential envoy to you; be wary in mixing and associating with him, and give him sound counsel. When he presents himself before you to deliver his message, let him say what he has to say in the presence of your grandees and nobles, and in a meeting of your wise counsellors.
