This Dua is taken from Al-Sahifa al-Sajjadiyya (The Psalms of Islam) AL-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 was composed by the Prophet’s great grandson, `Ali ibn al-Husayn, known as Zayn al-'Abidin (the adornment of the worshippers'), and has been cherished in Shi'ite sources from earliest times. Zayn al-'Abidin 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. The title Al-Sahifat al-Sajjadiyya means simply `The Book of al-Sajjad'. Al-Sajjad is one of the titles given to Zayn al-'Abidin and signifies `the one who constantly prostrates himself in prayer'. The book is often called Al-Sahifat al-Kamilat al-Sajjadiyya, that is, `The "Perfect", or "Complete", Book of al-Sajjad'. The Sahifa has been called by various honorifics, such as `Sister of the Qur'an', `Gospel of the Folk of the House', and `Psalms of the Household of Muhammad'.
