عَنْ عِمْرَانَ بْنِ حُصَيْنٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَا تَزَالُ طَائِفَةٌ مِنْ أُمَّتِي يُقَاتِلُونَ عَلَى الْحَقِّ ظَاهِرِينَ عَلَى مَنْ نَاوَأَهُمْ حَتَّى يُقَاتِلَ آخِرُهُمُ الْمَسِيحَ الدَّجَّالَ» . رَوَاهُ أَبُو دَاوُد

Abu Umama reported the Prophet as saying, “He who does not join a war-like expedition, or equip a warrior, or look well after a warrior’s family when he is away, will be smitten by God with a sudden calamity before the day of resurrection.” Abu Dawud transmitted it.
