Narrated Qais:
حَدَّثَنَا مُحَمَّدٌ ، حَدَّثَنَا عَبْدَةُ ، عَنِ ابْنِ أَبِي خَالِدٍ ، عَنْ قَيْسٍ ، قَالَ أَتَيْنَا خَبَّابَ بْنَ الأَرَتِّ نَعُودُهُ وَقَدِ اكْتَوَى سَبْعًا فَقَالَ لَوْلاَ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَانَا أَنْ نَدْعُوَ بِالْمَوْتِ لَدَعَوْتُ بِهِ .
We went to pay a visit to Khabbab bin Al-Art and he had got himself branded at seven spots over his body. He said, "If Allah's Messenger (ﷺ) had not forbidden us to invoke Allah for death, I would have invoked for it."
