The Prophet ﷺ said, "Whoever guarantees me (the chastity of) what is between his legs (i.e. his private parts), and what is between his jaws (i.e., his tongue), I guarantee him Paradise." (Using translation from Bukhārī 6807)

قَالَ رَسُولُ اللَّهِ ﷺ «مَنْ تَوَكَّلَ لِي مَا بَيْنَ لَحْيَيْهِ وَمَا بَيْنَ رِجْلَيْهِ تَوَكَّلْتُ لَهُ بِالْجَنَّةِ»
