The Messenger of Allah ﷺ said, "Whoever Allah protects from the evil of what is between his jaws and the evil of what is between his legs will enter Paradise."
قال رسول الله ﷺ: من وقاه الله شر ما بين لحييه، وشر ما بين رجليه دخل الجنة.
Tirmidhi (2409) narrated it, and Ibn Hibban (5703) graded it sahih, both from the hadith of Abu Khalid Ahmar, from Ibn Ajlan, from Abu Hazim, from Abu Hurairah, and he related it. Tirmidhi said, "This is a hasan gharib hadith," and said, "Abu Hazim who narrated from Abu Hurairah, his name is Salman, the client of Azza Ashjaiyyah, and he is Kufan, while Abu Hazim who narrated from Sahl bin Saad is Abu Hazim the ascetic, a Madinan, whose name is Salama bin Dinar."I say, its chain is hasan because of Ibn Ajlan, for he is hasan al-hadith. Hakim also recorded it (4/357) through the route of Ibn Ajlan as a suspended chain, and he narrated it as a connected chain from Wahib, from Abu Waqid, from Ishaq the client of Zaida, from Muhammad bin Abdul-Rahman bin Thawban, from Abu Hurairah, and he said, "Its chain is sahih, and Abu Waqid is Salih bin Muhammad."
