Abu Hurairah reported the Prophet ﷺ as saying “He who dies without having fought or having felt fighting (against the infidels) to be his duty will die guilty of a kind of hypocrisy.”
عَنِ النَّبِيِّ ﷺ قَالَ مَنْ مَاتَ وَلَمْ يَغْزُ وَلَمْ يُحَدِّثْ نَفْسَهُ بِالْغَزْوِ مَاتَ عَلَى شُعْبَةٍ مِنْ نِفَاقٍ
