باب الدُّعَاءِ بِالْمَوْتِ وَالْحَيَاةِ
Sahih al-Bukhari 6350

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 صلى الله عليه وسلم نَهَانَا أَنْ نَدْعُوَ بِالْمَوْتِ لَدَعَوْتُ بِهِ‏.‏
