Compiled by Imam Yahya ibn Sharaf al-Nawawi
وعن أبى هريرة رضي الله عنه قال: سئل رسول الله صلى الله عليه وسلم عن أكثر ما يدخل الناس الجنة؟ قال: “تقوى الله وحسن الخلق” وسئل عن أكثر ما يدخل الناس النار، قال: “الفم والفرج”. ((رواه الترمذي وقال: حديث حسن صحيح)).
Messenger of Allah (ﷺ) was asked about the deed which will be foremost to lead a man to Jannah. He replied, "Fear of Allah and the good conduct." Then he was asked about indulgence which will admit a man to Hell (Fire) and he answered, "The tongue and the genitals."[At- Tirmidhi, who classified it as Hadith Hasan Sahih].
