11ـ أَحْمَدُ بْنُ إِدْرِيسَ عَنْ مُحَمَّدِ بْنِ أَحْمَدَ رَفَعَهُ قَالَ قَالَ أَبُو عَبْدِ الله (عَلَيْهِ الْسَّلام) إِذَا شَكَكْتَ فِي تَسْبِيحِ فَاطِمَةَ الزَّهْرَاءِ (عَلَيْهِا الْسَّلام) فَأَعِدْ.
11. Ahmad ibn Idris from Muhammad ibn Ahmad in a marfu‘ manner has said the following: “Abu ‘Abd Allah (a.s.), has said, ‘If you face uncertainty about Tasbih of Fatimah al- Zahra’, ‘Alayha al-Salam, say it again.’”
