Jami` at-Tirmidhi, Volume 4, Book 25, Hadith 2004 (DarusSalam) ⓘ
Abu Hurairah narrated that the Messenger of Allah was asked about that for which people are admitted into Paradise the most, so he said: "Taqwa of Allah, and good character." And he was asked about that for which people are admitted into the Fire the most, and he said: " The mouth and the private parts."
حَدَّثَنَا أَبُو كُرَيْبٍ، مُحَمَّدُ بْنُ الْعَلاَءِ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ إِدْرِيسَ، حَدَّثَنِي أَبِي، عَنْ جَدِّي، عَنْ أَبِي هُرَيْرَةَ، قَالَ سُئِلَ رَسُولُ اللَّهِ صلى الله عليه وسلم عَنْ أَكْثَرِ مَا يُدْخِلُ النَّاسَ الْجَنَّةَ فَقَالَ " تَقْوَى اللَّهِ وَحُسْنُ الْخُلُقِ " . وَسُئِلَ عَنْ أَكْثَرِ مَا يُدْخِلُ النَّاسَ النَّارَ فَقَالَ " الْفَمُ وَالْفَرْجُ " . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ صَحِيحٌ غَرِيبٌ وَعَبْدُ اللَّهِ بْنُ إِدْرِيسَ هُوَ ابْنُ يَزِيدَ بْنِ عَبْدِ الرَّحْمَنِ الأَوْدِيُّ .
