The Chachnāma (Fatḥnāma-yi Sind) 35.1.5

35.1.5

You should exercise proper discretion and discrimination and should not consider high and low equal or on the same footing; for, that will show a weakness of reason and sense, and the enemy will attribute it to languor and indolence. I swear by my soul and by my head, that the great and glorious God has given you good counsels to follow and placed reason in you to guide you. It shows deficiency of courage to be lenient and merciful to each and all. Tell this to your officers and to your friends, who are attached to you. It is strange that after gaining the upper hand and subduing the enemy, you have so long remained inactive and have been showing mercy to them. It is such a long time since you have been sitting in one place just opposite your enemy. If they are straightforward and are really anxious for mercy and have no treachery in their hearts, let them desist from fighting. Then only practical means will be found to meet the expenditure of the war, and this prolonged enterprise will come to an end. I cannot but feel surprise at the weakness and indiscreetness of your policy. People will believe that you are trying to bring about peace and they will attribute your present conduct to lethargy and want of judgment. In this way no object will be gained. You ought not to give up the ways of imperialism and strong handed domination, and you should exercise discretion and inspire awe in order to subdue the enemy completely.
