Dr. Junaid Ali Haider’s Ṣaḥīfa Sayyidah Zaynab bint ʿAlī bin Abī Ṭālib (ʿalayhā al-salām) is indeed the first work in 1400 years of Ahl al-Sunnah scholarship to compile and present the narrations, sayings, and virtues of Sayyida Zaynab (alayhā al-salām) from authentic Sunni sources in a musnad-style format.
It represents a groundbreaking Sunni scholarly contribution, highlighting Sayyida Zaynab’s knowledge, eloquence, and spiritual status through verified historical and hadith references—something that had never been systematically done before in Sunni tradition.
