Narrated Sahl bin Sa`d:
حَدَّثَنَا مُحَمَّدُ بْنُ أَبِي بَكْرٍ ، حَدَّثَنَا عُمَرُ بْنُ عَلِيٍّ . وَحَدَّثَنِي خَلِيفَةُ ، حَدَّثَنَا عُمَرُ بْنُ عَلِيٍّ ، حَدَّثَنَا أَبُو حَازِمٍ ، عَنْ سَهْلِ بْنِ سَعْدٍ السَّاعِدِيِّ ، قَالَ النَّبِيُّ صلى الله عليه وسلم " مَنْ تَوَكَّلَ لِي مَا بَيْنَ رِجْلَيْهِ وَمَا بَيْنَ لَحْيَيْهِ، تَوَكَّلْتُ لَهُ بِالْجَنَّةِ " .
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."
