Sahih al-Bukhari 6430
Narrated Qais:
I heard Khabbab, who had branded his `Abdomen with seven brands, saying, "Had Allah's Messenger (ﷺ) 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 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.‏
