Al-Kāfi|Volume 3|Book 4|Chapter 27
14ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ أَنَّ بَعْضَ أَصْحَابِنَا كَتَبَ إِلَى أَبِي الْحَسَنِ الْمَاضِي (عَلَيْهِ الْسَّلام) يَسْأَلُهُ عَنِ الصَّلاَةِ عَلَى الزُّجَاجِ قَالَ فَلَمَّا نَفَذَ كِتَابِي إِلَيْهِ تَفَكَّرْتُ وَقُلْتُ هُوَ مِمَّا أَنْبَتَتِ الأرْضُ وَمَا كَانَ لِي أَنْ أَسْأَلَهُ عَنْهُ قَالَ فَكَتَبَ إِلَيَّ لاَ تُصَلِّ عَلَى الزُّجَاجِ وَإِنْ حَدَّثَتْكَ نَفْسُكَ أَنَّهُ مِمَّا أَنْبَتَتِ الأرْضُ وَلَكِنَّهُ مِنَ الْمِلْحِ وَالرَّمْلِ وَهُمَا مَمْسُوخَانِ.
14. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn who has said the following: “Certain ones of our people wrote to abu al-Hassan, the previous one عليه السلام, asking about Salah (prayer) on glass. He has said that when my letter finished I thought and said to myself that it is something that grows from earth, so I do not need to write and ask him (the Imam). He (the Imam) wrote to me, ‘You must not perform Salah (prayer) on glass even though your soul has spoken to you that it is of what earth grows. However, it is from salt and sand and they both are metamorphosed.’”
