This book is a collection of rules that govern the rituals of Hajj, as per the opinions of one of the most senior jurists of the day; Grand Ayatollah Sayyed Mohammad Taqi Al-Modarresi. Grand Ayatollah Sayyed Mohammad Taqi AlModarresi has a truly unique perspective on Hajj, in that not only is he a scholar who has acquired a vast wealth of knowledge through decades of research and teaching at the highest levels of Islamic jurisprudence, but has himself performed the Hajj pilgrimage over fifty times. Year after year, through half a century of tumultuous times, Ayatollah Al-Modarresi has experienced the challenges first hand, and has been able to provide solutions to those challenges, while remaining true to the scriptural sources; the Qur'an and the traditions of the Ahlulbayt.
