١٠ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ مُحَمَّدِ بْنِ سِنَانٍ عَنِ ابْنِ مُسْكَانَ قَالَ بَعَثْتُ بِمَسْأَلَةٍ إِلَى أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) مَعَ إِبْرَاهِيمَ بْنِ مَيْمُونٍ قُلْتُ سَلْهُ عَنِ الرَّجُلِ يَبُولُ فَيُصِيبُ فَخِذَهُ قَدْرُ نُكْتَةٍ مِنْ بَوْلِهِ فَيُصَلِّي وَيَذْكُرُ بَعْدَ ذَلِكَ أَنَّهُ لَمْ يَغْسِلْهَا قَالَ يَغْسِلُهَا وَيُعِيدُ صَلاَتَهُ.
10. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Muhammad ibn Sinan from ibn Muskan who has said the following: “I once sent a question to abu ‘Abd Allah , through Ibrahim ibn Maymun and told him to ask him (the Imam) about the case of a drop of urine found on one’s thigh but one performs Salah (prayer) and then remembers that he has not washed it. He (the Imam) said, ‘He is required to perform his Salah (prayer) again.’”
