Abu Hurayra reported that the Prophet, (ﷺ), said, "Do you know what it is that makes most people enter Hellfire?" "Allah and His Messenger know best," they said. He said, "The two empty ones:

the genitals and the mouth. Do you know what it is that makes most people enter Paradise? Taqwa of Allah and good character."

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.‏
