Hadith #9

9ـ حُمَيْدُ بْنُ زِيَادٍ عَنِ الْحَسَنِ بْنِ مُحَمَّدٍ عَنْ وُهَيْبِ بْنِ حَفْصٍ عَنْ أَبِي بَصِيرٍ قَالَ سَأَلْتُ أَبَا عَبْدِ الله (عَلَيْهِ الْسَّلام) عَنْ مِيتَةِ الْمُؤْمِنِ فَقَالَ يَمُوتُ الْمُؤْمِنُ بِكُلِّ مِيتَةٍ يَمُوتُ غَرَقاً وَيَمُوتُ بِالْهَدْمِ وَيُبْتَلَى بِالسَّبُعِ وَيَمُوتُ بِالصَّاعِقَةِ وَلاَ تُصِيبُ ذَاكِرَ الله تَعَالَى.

9. Humayd ibn Ziyad has narrated from al-Hassan ibn Muhammad from Wuhayb ibn Hafs from abu Basir who has said the following: “Once I asked abu ’Abd Allah, ‘Alayhi al-Salam, about the death of a believing person. The Imam said, ‘A believing person may die by any form of death, such as by drowning, or collapse of a house, by beasts or thunderous lightening but not when speaking of Allah.’”
