So travel freely, [O disbelievers], throughout the land [during] four months but (9:2)

﴿فَسِيحُوا فِي الْأَرْضِ أَرْبَعَةَ أَشْهُرٍ وَاعْلَمُوا أَنَّكُمْ غَيْرُ مُعْجِزِي اللَّهِ ۙ وَأَنَّ اللَّهَ مُخْزِي الْكَافِرِينَ﴾
[ التوبة: 2]

9:2 So travel freely, [O disbelievers], throughout the land [during] four months but know that you cannot cause failure to Allah and that Allah will disgrace the disbelievers.

So travel freely - O idolaters - on earth for a period of four months after which there will be no treaty nor any indemnity.
Be certain that you will never escape Allah’s punishment and retribution if you continue to disbelieve in Him.
Also be certain that Allah will humiliate the disbelievers, by their being killed or taken captive in the world, and by their entering the fire on the Day of Rising.
This includes those who broke their treaties as well as those who had open treaties without any fixed period.
As for those with whom you made a treaty for a fixed period their treaty will be honoured until the end of the specified period, even if this is longer than four months.

So travel freely (O Mushrikun - see V. 2:105) for four months (as you will) throughout the land, but know that you cannot escape (from the Punishment of) Allah, and Allah will disgrace the disbelievers.
