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 Glorification (Tasbih) of Fatima(a) during every day at the end of every prayer is more beloved to me than one thousand rak’as of prayer in every day

al-Kafi, v. 3, p. 343
