Hadith

Imam Sadiq (pbuh)

  تسْبِيحُ فَاطِمَةَ عَلَيْهَا اَلسَّلاَمُ فِي كُلِّ يَوْمٍ فِي دُبُرِ كُلِّ صَلاَةٍ أَحَبُّ إِلَيَّ مِنْ صَلاَةِ أَلْفِ رَكْعَةٍ فِي كُلِّ يَوْمٍ
The Tasbih Fatima al-Zahra (as) after every prayer is more beloved to me than one thousand Rak‘at prayer in every day

al-Kafi, v. 3, p. 343
