Mishkat al-Masabih 19 Jihad كتاب الجهاد 27

وَعَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ مَاتَ وَلَمْ يَغْزُو وَلَمْ يُحَدِّثْ بِهِ نَفْسَهُ مَاتَ عَلَى شُعْبَةٍ نفاق» . رَوَاهُ مُسلم

Abu Huraira reported God’s Messenger as saying, “He who dies without having fought, or having felt it to be his duty will die guilty of a kind of hypocrisy.” Muslim transmitted it.
