(Al-Hajj) 22 : 39
أُذِنَ لِلَّذِينَ يُقَاتَلُونَ بِأَنَّهُمْ ظُلِمُوا ۚ وَإِنَّ اللَّهَ عَلَىٰ نَصْرِهِمْ لَقَدِيرٌ
The permission for fighting has been granted to those who are being harmed in unjust; and indeed Lord Allah is capable to help them.
Today, as there is no group of believers anywhere in the world, there is no war and Jihad with weapons. So the odd believer will do Jihad with Adhikr against the hypocrites and Kuffar as explained in verse 9: 73. He will propagate Adhikr to entire worlds for keeping the universe in its equilibrium as explained in verse 2: 62. Whoever holdfasts Adhikr will safeguard him from all calamities, disasters, diseases, and Hellfire. See explanation 2: 216 and 4: 75-77.
