Imam Ahmad : 18937

حَدَّثَنَاه يَزِيدُ قَالَ أَخْبَرَنَا أَبُو الْأَشْهَبِ عَنْ أَبِي الْحَكَمِ الْبُنَانِيِّ عَنْ أَبِي بَرْزَةَ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ إِنَّ مِمَّا أَخْشَى عَلَيْكُمْ شَهَوَاتِ الْغَيِّ فِي بُطُونِكُمْ وَفُرُوجِكُمْ وَمُضِلَّاتِ الْهَوَى

Has narrated a hadith to us [Yazid] has informed us [Abul Asyhab] from [Abul Hakam Al Bunany] from [Abu Barzah] from the Prophet Peace be upon him, he said: "Truly what I very much fear from you all is the vile lust from the stomach, and your private parts, as well as the misguiding whims.
