عَنْهُ عَنْ صَفْوَانَ عَنِ اِبْنِ مُسْكَانَ عَنِ اَلْحَلَبِيِّ قَالَ: سَأَلْتُ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ عَنِ اَلْمَسْحِ عَلَى اَلْخُفَّيْنِ فَقَالَ «لاَ تَمْسَحْ» وَ قَالَ« إِنَّ جَدِّي قَالَ« سَبَقَ اَلْكِتَابُ اَلْخُفَّيْنِ»».
Safwan narrated from Ibn Muskan, from al-Halabi:
I asked Abu Abdillah عليه السلام about wiping over leather socks. Imam عليه السلام said: "Do not wipe (over leather socks)." And Imam عليه السلام said: "Indeed, my grandfather (The Prophet صلى الله عليه وعلى آله وسلم) said, 'The Book (Quran) has already preceded regarding the leather socks.'"
