فَسِيحُواْ فِي ٱلۡأَرۡضِ أَرۡبَعَةَ أَشۡهُرٖ وَٱعۡلَمُوٓاْ أَنَّكُمۡ غَيۡرُ مُعۡجِزِي ٱللَّهِ وَأَنَّ ٱللَّهَ مُخۡزِي ٱلۡكَٰفِرِينَ ٢
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.
Translation: Saheeh International (English)
Each word's meaning and sound
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.
