وَأَمَّا مَا رَوَاهُ سَعْدٌ عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ مُحَمَّدِ بْنِ إِسْمَاعِيلَ بْنِ بَزِيعٍ عَنْ ظَرِيفِ بْنِ نَاصِحٍ عَنْ ثَعْلَبَةَ بْنِ مَيْمُونٍ عَنْ عَبْدِ اَللَّهِ بْنِ يَحْيَى عَنِ اَلْحُسَيْنِ بْنِ عَبْدِ اَللَّهِ قَالَ: سَأَلْتُ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ عَنِ اَلرَّجُلِ يَمْسَحُ رَأْسَهُ مِنْ خَلْفِهِ وَ عَلَيْهِ عِمَامَةٌ بِإِصْبَعِهِ أَ يُجْزِيهِ ذَلِكَ فَقَالَ« نَعَمْ».
As for the report narrated by Saʿd, from Ahmad ibn Muhammad, from Muhammad ibn Ismaʿil ibn Baziʿ, from Zarif ibn Nasih, from Thaʿlabah ibn Maymun, from Abdullah ibn Yahya, from al-Husayn ibn Abdullah, who said:
I asked Abu Abdullah عليه السلام about a man who wipes his head from the back while wearing a turban, using his finger. I asked: "Does this suffice?" Imam عليه السلام said: "Yes."
