٢٠ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ مُوسَى عَنْ يَعْقُوبَ بْنِ يَزِيدَ عَنْ عُثْمَانَ بْنِ عِيسَى عَنْ عَبْدِ الصَّمَدِ بْنِ بَشِيرٍ عَنْ حُذَيْفَةَ بْنِ مَنْصُورٍ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ قَالَ الْعُطَاسُ يَنْفَعُ فِي الْبَدَنِ كُلِّهِ مَا لَمْ يَزِدْ عَلَى الثَّلاثِ فَإِذَا زَادَ عَلَى الثَّلاثِ فَهُوَ دَاءٌ وَسُقْمٌ.
20. Muhammad ibn Yahya has narrated from Muhammad ibn Musa from Ya’qub ibn Yazid from ‘Uthman ibn ‘Isa from ‘Abd al-Samad ibn Bash ‘Amir from Hudhayfah ibn Mansur from Abu ‘Abdillah  who has said the following: “Sneezing is beneficial to all parts of the body if it is not more than three times, if it is more than three times then it is an illness and disease.’”
