5ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ عُمَرَ بْنِ أُذَيْنَةَ عَنِ الْفُضَيْلِ بْنِ يَسَارٍ وَبُرَيْدِ بْنِ مُعَاوِيَةَ عَنْ أَحَدِهِمَا (عَلَيْهِما الْسَّلام) قَالَ
لاَ بَأْسَ بِالْقِيَامِ عَلَى الْمُصَلَّى مِنَ الشَّعْرِ وَالصُّوفِ إِذَا كَانَ يَسْجُدُ عَلَى الأرْضِ فَإِنْ كَانَ مِنْ نَبَاتِ الأرْضِ فَلاَ بَأْسَ بِالْقِيَامِ عَلَيْهِ وَالسُّجُودِ عَلَيْهِ.
5. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from ‘Umar ibn ’Udhaynah from Fudayl ibn Yasar and Burayd ibn Mu‘awiyah who has said the following: “One of the two Imam, ‘Alayhim al-Salam, has said,
‘It is not harmful to stand on a prayer mat made of hairs and wool if one performs Sajdah (prostration) on earth, but if it is of the plants of earth, it is not harmful to stand on it and perform Sajdah (prostration) on it.’”
