Supplication for death

Isma'il ibn Qays said, "I came to Khabbab when he had been cauterised seven times. He said, 'If it had not been that the Messenger of Allah ﷺ had forbidden us to pray for death, I would have done so.'"

حَدَّثَنَا مُسَدَّدٌ، قَالَ: حَدَّثَنَا يَحْيَى، عَنْ إِسْمَاعِيلَ قَالَ: حَدَّثَنِي قَيْسٌ قَالَ: أَتَيْتُ خَبَّابًا، وَقَدِ اكْتَوَى سَبْعًا، وَقَالَ: لَوْلاَ أَنَّ رَسُولَ اللهِ ﷺ نَهَانَا أَنْ نَدْعُوَ بِالْمَوْتِ لَدَعَوْتُ بِهِ.
