Tahdhīb al-Aḥkām|Volume 1|Book 1|Chapter 4
وَ بِهَذَا اَلْإِسْنَادِ عَنِ اَلْحُسَيْنِ بْنِ سَعِيدٍ عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ قَالَ: سَأَلْتُ أَبَا اَلْحَسَنِ عَلَيْهِ اَلسَّلاَمُ عَنِ اَلْمَسْحِ عَلَى اَلْقَدَمَيْنِ كَيْفَ هُوَ فَوَضَعَ كَفَّهُ عَلَى اَلْأَصَابِعِ ثُمَّ مَسَحَهَا إِلَى اَلْكَعْبَيْنِ فَقُلْتُ لَهُ لَوْ أَنَّ رَجُلاً قَالَ بِإِصْبَعَيْنِ مِنْ أَصَابِعِهِ هَكَذَا إِلَى اَلْكَعْبَيْنِ قَالَ« لاَ إِلاَّ بِكَفِّهِ كُلِّهَا».
Through the same chain of narrators, from Al-Husayn bin Sa‘id, from Ahmad bin Muhammad, who said:
(Narrator said) “I asked Abu Al-Hasan عليه السلام about wiping over the feet. How is it done?” Imam عليه السلام placed his palm on the toes and then wiped it to the ankles. I asked Imam عليه السلام: "What if a person wiped with two fingers from his toes to his ankles like this?" Imam عليه السلام said: "No, it must be with the entire palm."
