Hadith 12153ـ الْحُسَيْنُ بْنُ مُحَمَّدٍ عَنْ عَبْدِ الله بْنِ عَامِرٍ عَنْ عَلِيِّ بْنِ مَهْزِيَارَ عَنْ مُحَمَّدِ بْنِ إِسْمَاعِيلَ قَالَ رَأَيْتُ أَبَا الْحَسَنِ (عَلَيْهِ الْسَّلام) إِذَا سَجَدَ يُحَرِّكُ ثَلاَثَ أَصَابِعَ مِنْ أَصَابِعِهِ وَاحِدَةً بَعْدَ وَاحِدَةٍ تَحْرِيكاً خَفِيفاً كَأَنَّهُ يَعُدُّ التَّسْبِيحَ ثُمَّ رَفَعَ رَأْسَهُ.
3. Al-Husayn ibn Muhammad has narrated from ‘Abd Allah ibn ‘Amir from Ali ibn Mahziyar from Muhammad ibn Isma’il who has said the following: “I saw abu al-Hassan (a.s.), when prostrating, move three of his fingers one after the other slightly as if counting rosary and then raise his head from prostration.”
