مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ رَفَعَهُ إِلَى أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ
قَالَ لَا يَزْدَرِدَنَّ أَحَدُكُمْ مَا يَتَخَلَّلُ بِهِ فَإِنَّهُ يَكُونُ مِنْهُ الدُّبَيْلَةُ .
4. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad in a marfu‘ manner who has said the following:
“Abu ‘Abd Allah 
, has said, ‘Do not take light what you use as a toothpick, it can cause a boil in one’s belly (that may cause one’s death).”’
