"Whoever kills himself with (an instrument of)iron, his iron will be in his hand, to continually stab himself in his stomach with it, in the fire of Jahannam, dwelling in that state eternally. And whoever kills himself with poison, then his poison will be in his hand, to continually take it in the Fire of Jahannam, dwelling in that state eternally. And whoever throws himself from a mountain to kill himself, then he will be continually throwing himself in the Fire of Jahannam, dwelling in that state eternally"
حَدَّثَنَا مَحْمُودُ بْنُ غَيْلاَنَ، حَدَّثَنَا أَبُو دَاوُدَ، عَنْ شُعْبَةَ، عَنِ الأَعْمَشِ، قَالَ سَمِعْتُ أَبَا صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ مَنْ قَتَلَ نَفْسَهُ بِحَدِيدَةٍ فَحَدِيدَتُهُ فِي يَدِهِ يَتَوَجَّأُ بِهَا فِي بَطْنِهِ فِي نَارِ جَهَنَّمَ خَالِدًا مُخَلَّدًا فِيهَا أَبَدًا وَمَنْ قَتَلَ نَفْسَهُ بِسُمٍّ فَسُمُّهُ فِي يَدِهِ يَتَحَسَّاهُ فِي نَارِ جَهَنَّمَ خَالِدًا مُخَلَّدًا فِيهَا أَبَدًا وَمَنْ تَرَدَّى مِنْ جَبَلٍ فَقَتَلَ نَفْسَهُ فَهُوَ يَتَرَدَّى فِي نَارِ جَهَنَّمَ خَالِدًا مُخَلَّدًا فِيهَا أَبَدًا .
