حَدَّثَنِي يَحْيَى بْنُ مُوسَى، حَدَّثَنَا وَكِيعٌ، حَدَّثَنَا إِسْمَاعِيلُ، عَنْ قَيْسٍ، قَالَ سَمِعْتُ خَبَّابًا، وَقَدِ اكْتَوَى يَوْمَئِذٍ سَبْعًا فِي بَطْنِهِ وَقَالَ لَوْلاَ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَانَا أَنْ نَدْعُوَ بِالْمَوْتِ لَدَعَوْتُ بِالْمَوْتِ، إِنَّ أَصْحَابَ مُحَمَّدٍ صلى الله عليه وسلم مَضَوْا وَلَمْ تَنْقُصْهُمُ الدُّنْيَا بِشَىْءٍ، وَإِنَّا أَصَبْنَا مِنَ الدُّنْيَا مَا لاَ نَجِدُ لَهُ مَوْضِعًا إِلاَّ التُّرَابَ‏.‏
