The opening as it read in 2005

Sahifa al-Sajjadiyya is the oldest prayer manual in Islamic sources and one of the most seminal works of Islamic spirituality of the early period. It is also known as Sahifa-e-Kamila .1 It was composed by the Prophet's great grandson, Ali ibn Husayn ( 658 - 713 ), also known as Zainul Abideen ('the adornment of the worshippers'), and has been cherished in Shi'ite sources from earliest times. Zainul Abideen was the fourth of the Shi'ite Imams , after his father Husayn , his uncle Hasan , and his grandfather Ali , the Prophet's son-in-law. Shi'ite tradition considers the Sahifa a book worthy of the utmost veneration, ranking it behind only the Qur'an and Ali's Nahj al Balagha .2
