In his book The Prophet of Peace, Khan writes that the greatest fallacy entertained by people of a militant cast of minds is that they think true peace is accompanied by justice. Khan objects to the mentality of “peace without justice is no peace at all.”
Khan says that such people ought, but seem not to know, that in this world, peace is simply a state in which the disturbances of warfare and social unrest are mercifully absent but in which there is no sure guarantee of justice. “They should understand that, primarily, what the establishment of peace does is open up opportunities for the kind of constructive work to be carried out which can seldom be accomplished in a situation where there is the continual dislocation caused by clash and confrontation. A major part of that construction work is putting in place a system of justice. For it must be borne in mind that justice is not a direct result of peace. It is only by availing of the opportunities offered by the peace that we can achieve what is called justice,” writes Khan in chapter 20 of his book. According to Khan, the maxim to follow when peace is desired in the state is: ‘Ignore the problems and avail the opportunities. This ideology of peace can counter the ideology of violence, based on the sources of Islam.’

Khan says that the life of the Prophet of Islam provides a telling example of this wisdom. 
Khan further talks about the treaty of Hudaybiya. Here is an excerpt from his book, where Khan explains how this treaty brokered peace. 

The Hudaybiya treaty is, in fact, a peace treaty that was concluded not by receiving justice but rather by leaving out justice. All the conditions of this treaty were unilateral, giving concessions to the Makkan non-Muslims. None of these conditions were in favor of the Muslims. For instance, one article of this treaty was that the Prophet would not insist on going to Makkah to perform Umrah but would instead go back to Madinah directly from Hudaybiya.
With this, Khan concludes that the Hudaybiya treaty was thus the equivalent of a 10-year no-war pact. It took the form of a written pledge from his opponents that they would not initiate any hostilities against him and that they would let him and his followers live in peace in Madinah.
