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.
