Compiled by Imam Yahya ibn Sharaf al-Nawawi
وعن سهل بن سعد قال: قال رسول الله صلى الله عليه وسلم: "من يضمن لي ما بين لحييه، وما بين رجليه أضمن له الجنة" ((متفق عليه)).
The Messenger of Allah (ﷺ) said, "Whosoever gives me a guarantee to safeguard what is between his jaws and what is between his legs, I shall guarantee him Jannah."[Al-Bukhari].
