أَخْبَرَنَا الْقَاسِمُ بْنُ كَثِيرٍ قَالَ سَمِعْتُ عَبْدَ الرَّحْمَنِ بْنَ شُرَيْحٍ يُحَدِّثُ أَنَّهُ سَمِعَ سَهْلَ بْنَ أَبِي أُمَامَةَ بْنِ سَهْلِ بْنِ حُنَيْفٍ يُحَدِّثُ عَنْ أَبِيهِ عَنْ جَدِّهِ قَالَ

إِنَّ رَسُولَ اللَّهِ ﷺ قَالَ «مَنْ سَأَلَ اللَّهَ الشَّهَادَةَ صَادِقًا مِنْ قَلْبِهِ بَلَّغَهُ اللَّهُ مَنَازِلَ الشُّهَدَاءِ وَإِنْ مَاتَ عَلَى فِرَاشِهِ» – إسناده صحيح
