At-Tawbah 9:2

Faseehoo fee al-ardi arbaAAataashhurin waAAlamoo annakum ghayru muAAjizee Allahiwaanna Allaha mukhzee alkafireen

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

So, move in the land freely for four months, and be aware that you can never frustrate Allah, and that Allah is going to disgrace the disbelievers.
