Arabic (Original)
حَدَّثَنَا عَفَّانُ حَدَّثَنَا عُمَرُ بْنُ عَلِيٍّ قَالَ سَمِعْتُ أَبَا حَازِمٍ عَنْ سَهْلِ بْنِ سَعْدٍ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ مَنْ تَوَكَّلَ لِي مَا بَيْنَ لَحْيَيْهِ وَمَا بَيْنَ رِجْلَيْهِ تَوَكَّلْتُ لَهُ بِالْجَنَّةِ.
English Translation
Affan narrated to us: Umar ibn Ali narrated to us, he said: I heard Abu Hazim, from Sahl ibn Sa'd, from the Prophet, peace and blessings be upon him, who said: Whoever guarantees me what is between his jaws (his tongue) and what is between his legs (his private parts), I guarantee him Paradise.
