There is no Hijra now, but (only) Jihad (fighting for the cause of Islam) and sincerity of purpose (have great reward) ; when you are asked to set out (on an expedition undertaken for the cause of Islam) you should (readily) do so.
قَالَ رَسُولُ اللَّهِ ﷺ يَوْمَ الْفَتْحِ فَتْحِ مَكَّةَ لاَ هِجْرَةَ وَلَكِنْ جِهَادٌ وَنِيَّةٌ وَإِذَا اسْتُنْفِرْتُمْ فَانْفِرُوا
