Chapter on Supplication Between the Units of Prayer (Rak‘at)

Ali ibn Hatim, from Ahmad ibn Ali, from Ahmad ibn Ishaq, from Bakr ibn Muhammad, from Abu Abdillah عليه السلام, peace be upon him: Imam al-Sadiq عليه السلام said: “My face has prostrated to You عز وجل in servitude and humility. There is no God but You عز وجل, truly, truly. The First before everything, and the Last after everything. Here I am before You عز وجل, my forelock in Your hand so forgive me, for none forgives the great sins except You عز وجل. So forgive me, for I confess my sins against myself, and none can repel the great sin except You عز وجل.” Then raise your head from the prostration, and when you are upright standing, supplicate with whatever you wish.
