Narrated Qais:

I came to Khabbab who had been branded with seven brands over his abdomen, and I heard him saying, "If the Prophet: had not forbidden us to invoke (Allah) for death, I would have invoked Allah for it."

حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا يَحْيَى، عَنْ إِسْمَاعِيلَ، قَالَ حَدَّثَنِي قَيْسٌ، قَالَ أَتَيْتُ خَبَّابًا وَقَدِ اكْتَوَى سَبْعًا فِي بَطْنِهِ فَسَمِعْتُهُ يَقُولُ لَوْلاَ أَنَّ النَّبِيَّ ﷺ نَهَانَا أَنْ نَدْعُوَ بِالْمَوْتِ لَدَعَوْتُ بِهِ.
