مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ أَحْمَدَ عَنْ عُمَرَ بْنِ عَلِيِّ بْنِ عُمَرَ بْنِ يَزِيدَ عَنْ عَمِّهِ مُحَمَّدِ بْنِ عُمَرَ عَنْ بَعْضِ مَنْ حَدَّثَهُ أَنَّ أَبَا جَعْفَرٍ ( عليه السلام ) كَانَ يَقُولُ
مَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَ الْيَوْمِ الْآخِرِ فَلَا يَدْخُلِ الْحَمَّامَ إِلَّا بِمِئْزَرٍ، قال: فدخل ذات يوم الحمام فتنور فلما أن أطبقت النورة على بدنه ألقى المئزر فقال له مولى له: بأبي أنت وأمي إنك لتوصينا بالمئزر ولزومه وقد ألقيته عن نفسك؟ فقال: أما علمت أن النورة قد أطبقت العورة.
35. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ‘Umar ibn Ali ibn ‘Umar ibn Yazid from his uncle Muhammad ibn ‘Umar from those who narrated to him that Abu Ja‘far 
used to say,
"Whoever believes in Allah and the Last Day should not enter the bathhouse except with a waistcloth." One day, he entered the bathhouse and applied lime paste. When the paste covered his body, he removed the waistcloth. His servant said to him, "May my father and mother be your ransom, you advise us to keep the waistcloth, but you have removed it yourself?" He replied, "Don't you know that the lime paste has covered the private parts?"
