People of Jannah have taqwa of Allah and good conduct

"That for which people are admitted into Jannah the most are (1) taqwá (fear and consciousness) of Allah, and (2) good conduct. And that for which people are admitted into Hellfire the most are the two cavities: (1) the mouth, and (2) the private parts."

«أكثر ما يُدْخِلُ الناسَ الجنةَ: تقوى اللهِ وحُسْنُ الخُلِقُ، وأكثرُ ما يُدْخِل الناسَ النارَ: الأجوفان: الفمُ والفرجُ۔»
