“Whoever does not fight, or equip a fighter, or stay behind to look after a fighter’s family, Allah will strike him with a calamity before the Day of Resurrection.” (Using translation from Ibn Mājah 2762)  

أَنَّ النَّبِيَّ ﷺ قَالَ «مَنْ لَمْ يَغْزُ أَوْ يُجَهِّزْ غَازِيًا أَوْ يَخْلُفْ غَازِيًا فِي أَهْلِهِ بِخَيْرٍ أَصَابَهُ اللَّهُ بِقَارِعَةٍ قَبْلَ يَوْمِ الْقِيَامَةِ»
