Narrated Qais:

I heard Khabbab, who had branded his abdomen with seven brands, saying, "Had Allah's Apostle not forbidden us to invoke Allah for death, I would have invoked Allah for death. The companions of Muhammad have left this world without taking anything of their reward in it (i.e., they will have perfect reward in the Hereafter), but we have collected of the worldly wealth what we cannot spend but on earth (i.e. on building houses)."

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