6ـ الْحُسَيْنُ بْنُ مُحَمَّدٍ الأشْعَرِيُّ عَنْ عَبْدِ الله بْنِ عَامِرٍ عَنْ عَلِيِّ بْنِ مَهْزِيَارَ عَنْ فَضَالَةَ بْنِ أَيُّوبَ عَنْ عَبْدِ الله بْنِ سِنَانٍ قَالَ قَالَ أَبُو عَبْدِ الله (عَلَيْهِ الْسَّلام) مَنْ سَبَّحَ تَسْبِيحَ فَاطِمَةَ الزَّهْرَاءِ (عَلَيْهِا الْسَّلام) قَبْلَ أَنْ يَثْنِيَ رِجْلَيْهِ مِنْ صَلاَةِ الْفَرِيضَةِ غَفَرَ الله لَهُ وَلْيَبْدَأْ بِالتَّكْبِيرِ.
6. Al-Husayn ibn Muhammad al-Ash’ariy has narrated from ‘Abd Allah ibn ‘Amir from Ali ibn Mahziyar from Fadalah ibn Ayyub from ‘Abd Allah ibn Sinan who has said the following: “Abu ‘Abd Allah عليه السلام, has said, ‘One who reads Tasbih of Fatimah al-Zahra’, ‘Alayha al- Salam, after an obligatory Salah (prayer) and before moving his legs away from his position Allah forgives him and he should begin with al-Takbir (Allahu Akbar).”’
