Allah the Exalted orders His Messenger to perform Jihad against the disbelievers and hypocrites, the former with weapons and armaments and the later by establishing Allah's legislated penal code,

﴿وَاغْلُظْ عَلَيْهِمْ﴾

(and be severe against them) meaning, in this life,

﴿وَمَأْوَاهُمْ جَهَنَّمُ وَبِئْسَ الْمَصِيرُ﴾

(their abode will be Hell, and worst indeed is that destination.) that is, in the Hereafter.
