(At-Thahreem) 66 : 9
يَا أَيُّهَا النَّبِيُّ جَاهِدِ الْكُفَّارَ وَالْمُنَافِقِينَ وَاغْلُظْ عَلَيْهِمْ ۚ وَمَأْوَاهُمْ جَهَنَّمُ ۖ وَبِئْسَ الْمَصِيرُ

Oh you Prophet! Do Jihad against the Kuffar and the hypocrites, and be harsh upon them, and their abode is the Hell, and what an evil returning place.

Since it is commanded calling the prophet, it is the duty of believers who are one in thousand, to do great Jihad with Adhikr against the Fujjar who are the fuel of fire and are mentioned as the worthless people in verses 25: 17-18; and 48: 12. It is warned in verse 25: 30 that on the Day of Judgement, Messenger Muhammed by coming with Lord’s Bok will say against the Fujjar that it is because these my people neglected this Reading, they got this bad condition. It is told in verses 14: 28-30 that by converting the Favour of Allah into the disbelief, the Hypocrites have made halal-permitted-the house of worthless to their followers. See explanation 8: 22; 9: 73; and 48: 6, 29.
