Tahdhīb al-Aḥkām|Volume 1|Book 1|Chapter 12
وَ بِهَذَا اَلْإِسْنَادِ عَنْ مُحَمَّدِ بْنِ أَحْمَدَ بْنِ يَحْيَى عَنِ اَلْعَمْرَكِيِّ عَنْ عَلِيِّ بْنِ جَعْفَرٍ عَنْ مُوسَى بْنِ جَعْفَرٍ عَلَيْهِمَا اَلسَّلاَمُ قَالَ: سَأَلْتُهُ عَنِ اَلْبَوَارِي يُصِيبُهَا اَلْبَوْلُ هَلْ تَصْلُحُ اَلصَّلاَةُ عَلَيْهَا إِذَا جَفَّتْ مِنْ غَيْرِ أَنْ تُغْسَلَ قَالَ« نَعَمْ لاَ بَأْسَ».
And through this chain of transmission, from Muhammad bin Ahmad bin Yahya, from Al-Amraki, from Ali bin Ja’far, from Musa bin Ja’far عليه السلام:
I asked Imam عليه السلام about mats that are affected by urine - can prayer be performed on them if they dry without being washed? Imam عليه السلام said: "Yes, there is no harm."
