The Messenger of Allah was asked about that for which people are admitted into Paradise the most and he said, "Conciousness 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."
سُئِلَ رَسُولُ اللَّهِ ﷺ عَنْ أَكْثَرِ مَا يُدْخِلُ النَّاسَ الْجَنَّةَ فَقَالَ «تَقْوَى اللَّهِ وَحُسْنُ الْخُلُقِ۔» وَسُئِلَ عَنْ أَكْثَرِ مَا يُدْخِلُ النَّاسَ النَّارَ فَقَالَ: «الْفَمُ وَالْفَرْجُ۔»
