In particular, Shia tradition holds the book in great esteem, ranking it behind the Quran, the central religious text of Islam, and Nahj al-Balagha, which is attributed to the fourth Caliph and first Shia imam, Ali ibn Abi Talib.

[9] Muslims often recite the supplications of their religious authorities, starting with Muhammad and, for the Shia, continuing with their imams.

Once the worshipper admits his inadequacies and sinfulness, he can abase himself before his Lord and ask for His generosity and forgiveness.

[15] He thus frequently asks God for forgiveness in al-Sahifa, and so did Muhammad in his prayers, even though both figures are regarded as infallible in Shia Islam.

[18] Rather they repeatedly asked God to conceal (istighfar) their inadequacies as limited human beings.

[21] In al-Sahifa, al-Sajjad sometimes alludes to the injustices suffered by Muhammad's household, the Ahl al-Bayt.

[24] For instance, salutations to Muhammad and his family frequently appear in the book in defiance of Umayyad policies.

Its prayer, "Blessing Upon the Bearers of the Throne," for instance, summarizes Islamic views about angels.

[2] The attribution of al-Sahifa to al-Sajjad is often regarded as authentic,[6] although parts of the books may have been artistically edited by others.
