حَدَّثَنَا مُحَمَّدُ بْنُ سَلاَمٍ، عَنِ ابْنِ إِدْرِيسَ قَالَ: سَمِعْتُ أَبِي يُحَدِّثُ عَنْ جَدِّي، عَنْ أَبِي هُرَيْرَةَ: سُئِلَ رَسُولُ اللهِ صلى الله عليه وسلم: مَا أَكْثَرُ مَا يُدْخِلُ الْجَنَّةَ؟ قَالَ: تَقْوَى اللهِ، وَحُسْنُ الْخُلُقِ، قَالَ: وَمَا أَكْثَرُ مَا يُدْخِلُ النَّارَ؟ قَالَ: الأَجْوَفَانِ: الْفَمُ وَالْفَرْجُ.
