The most precious existential dimension of Fatima Zahra (peace be upon her) was due to "Allah's worship" and her infinite patience against the hardships of defending the guardainship (Velayat). In the ziyarah of Lady Fatimah al-Zahra (peace be upon her), we read that she is addressed as" O carefully examined (lady), Allah Who created you had tried you, before He created you (for this worldly life), and thus He found you successfully enduring in that trial."
Tahdhib al-Ahkam: 6/9 hadith 12
