١٣ـ مُحَمَّدُ بْنُ يَحْيَى عَنِ الْعَمْرَكِيِّ النَّيْسَابُورِيِّ عَنْ عَلِيِّ بْنِ جَعْفَرٍ عَنْ أَخِيهِ مُوسَى بْنِ جَعْفَرٍ (عَلَيْهِ الْسَّلام) قَالَ سَأَلْتُهُ عَنِ الرَّجُلِ يُصَلِّي عَلَى الرَّطْبَةِ النَّابِتَةِ قَالَ فَقَالَ إِذَا أَلْصَقَ جَبْهَتَهُ بِالأرْضِ فَلاَ بَأْسَ وَعَنِ الْحَشِيشِ النَّابِتِ الثَّيِّلِ وَهُوَ يُصِيبُ أَرْضاً جَدَداً قَالَ لاَ بَأْسَ.
13. Muhammad ibn Yahya has narrated from al-‘Amrakiy al-Naysaburiy from Ali ibn Ja’far from his brother Musa ibn Ja‘far, ‘Alayhim al-Salam, has said the following: “I once asked him (the Imam) , about a man who performs Sajdah (prostration) on wet growing items. He (the Imam) said, ‘If your forehead touches the ground it is not harmful.’ I asked about stationary grass on the ground and dry leaves while he touches the ground. He (the Imam) said, ‘It is not harmful.’”
