وَبِهَذَا اَلْإِسْنَادِ عَنِ اَلْحُسَيْنِ بْنِ سَعِيدٍ عَنْ صَفْوَانَ عَنِ اَلْعَلاَءِ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَحَدِهِمَا عَلَيْهِمَا اَلسَّلاَمُ قَالَ: سَأَلْتُهُ عَنِ اَلْمَسْحِ عَلَى اَلرِّجْلَيْنِ فَقَالَ« لاَ بَأْسَ».
Through the same chain of narrators, from Al-Husayn bin Sa‘id, from Safwan, from Al-‘Ala’, from Muhammad bin Muslim, from one of the two Imams عليه السلام, who said:
I asked Imam عليه السلام about wiping over the feet, and Imam عليه السلام said: 'There is no harm.'"
