ابن ماجة:١٥٢٥ – حَدَّثَنَا أَحْمَدُ بْنُ يُوسُفَ السُّلَمِيُّ حَدَّثَنَا مُسْلِمُ بْنُ إِبْرَاهِيمَ حَدَّثَنَا الْحَارِثُ بْنُ نَبْهَانَ حَدَّثَنَا عُتْبَةُ بْنُ يَقْظَانَ عَنْ أَبِي سَعِيدٍ عَنْ مَكْحُولٍ عَنْ وَاثِلَةَ بْنِ الأَسْقَعِ قَالَ

قَالَ رَسُولُ اللَّهِ ﷺ صَلُّوا عَلَى كُلِّ مَيِّتٍ وَجَاهِدُوا مَعَ كُلِّ أَمِيرٍ
