O Prophet, fight against the disbelievers and the hypocrites and be harsh upon them. And their refuge is Hell, and wretched is the destination.  

O Prophet, struggle against the disbelievers, with the sword, and the hypocrites, with words and ˹definitive˺ arguments, and be harsh with them, through rebuke and aversion ˹towards them˺; for their abode will be Hell, an evil journey’s end, ˹an evil˺ resort it is!
