Al-Adab Al-Mufrad
Book 14, Hadith 289
حَدَّثَنَا أَبُو نُعَيْمٍ، قَالَ: حَدَّثَنَا دَاوُدُ بْنُ يَزِيدَ قَالَ: سَمِعْتُ أَبِي يَقُولُ: سَمِعْتُ أَبَا هُرَيْرَةَ يَقُولُ: قَالَ النَّبِيُّ صلى الله عليه وسلم: تَدْرُونَ مَا أَكْثَرُ مَا يُدْخِلُ النَّارَ؟ قَالُوا: اللَّهُ وَرَسُولُهُ أَعْلَمُ، قَالَ: الأَجْوَفَانِ: الْفَرْجُ وَالْفَمُ، وَأَكْثَرُ مَا يُدْخِلُ الْجَنَّةَ؟ تَقْوَى اللهِ وَحُسْنُ الْخُلُقِ.

Abu Nu‘aym narrated to us: Dawud ibn Yazid narrated to us: I heard my father say: I heard Abu Hurayra say that the Prophet ﷺ said: ‘Do you know what most often brings people into the Fire?’ They said, ‘Allah and His Messenger know best.’ He said, ‘The two hollow parts: the genitals and the mouth.’ And what most often brings people into the Garden? ‘Reverence for Allah and good character.’
Notes and open questions — unreviewed
الأجوفان literally means ‘the two hollow ones’; the report identifies them as the genitals and the mouth. The question about Paradise is followed by its answer without a separately narrated response from the listeners.
الأَجْوَفَانِ
The dual form describes the two hollow parts, identified immediately as the genitals and mouth.
Would ‘two hollow parts’ be clearer and closer than the witness’s ‘two empty ones’?
