٣ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ إِبْرَاهِيمَ بْنِ أَبِي مَحْمُودٍ قَالَ سَمِعْتُ الرِّضَا (عَلَيْهِ الْسَّلام) يَقُولُ يُسْتَنْجَى وَيُغْسَلُ مَا ظَهَرَ مِنْهُ عَلَى الشَّرْجِ وَلاَ تُدْخَلُ فِيهِ الأنْمُلَةُ.
3. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ibrahim ibn abu Mahmud who has said the following: “I heard abu al-Hassan, al-Rida , say, ‘One should get rid of remaining feces and urine by washing what is outside of the buttocks and there is no need to enter one’s fingers inside.’”
