Hadith.960 - Imam (as) said: "When you finish the obligatory prayer, say: 'I am content with Allah (swt) as my Lord (azj), with Islam as my religion, with the Qur'an as my book, with Muhammad as my Prophet, with Ali as my guardian, and with Hasan, Hussain, Ali ibn al-Hussain, Muhammad ibn Ali, Ja'far ibn Muhammad, Musa ibn Ja'far, Ali ibn Musa, Muhammad ibn Ali, Ali ibn Muhammad, Hasan ibn Ali, and the Hujjah ibn al-Hasan (peace be upon them all) as Imams. O’ Allah (swt), protect Your guardian, the Hujjah, from all sides—from in front of him, behind him, on his right, on his left, above him, and below him. Extend his lifespan, make him the one to establish Your command, grant him victory for Your religion, and show him what pleases him and brings him joy in himself, his family, his progeny, his wealth, and his followers. Show him what frightens his enemies and demonstrate to his enemies what they fear. Heal the hearts of believers through him.'" The Prophet (sw) would say upon finishing his prayer: Allahumma ighfir li ma qaddamtu wa ma akhkhartu wa ma Asrartu wa ma a‘lantu wa israfi ‘ala nafsi wa ma anta a‘lamu bihi minni. Allahumma anta al-Muqaddimu wa anta al-Mu’akhkhiru, la ilaha illa anta. Bi‘ilmika al-ghayba wa biqudratika ‘ala al-khalqi ajma‘een, ma ‘alimta al-hayata khayran li fa-ahyini, wa tawaffani idha ‘alimta al-wafata khayran li. Allahumma inni as’aluka khashyataka fi as-sirri wa al-‘alaniyah, wa kalimata al-haqqi fi al-ghadabi wa ar-rida, wa al-qasda fi al-faqri wa al-ghina. Wa as’aluka na‘iman la yanfadu, wa qurrata ‘aynin la tanqati‘u. Wa as’aluka ar-rida bil-qada’, wa barda al-‘ayshi ba‘da al-mawt, wa ladhdhata an-nadhari ila wajhika wa shawqan ila liqa’ika, min ghayri darraa’a mudirrah wa la fitnatin mudhlimah. Allahumma zayinna bi-zinat al-iman, wa aj‘alna hudatan mahdiyyeen. Allahumma ihdina fi man hadayt. Allahumma inni as’aluka ‘azeemata ar-rashad, wa ath-thabata fi al-amri wa ar-rushda, wa as’aluka shukra ni‘matika wa husna ‘afiyatika wa ada’a haqqika. Wa as’aluka ya Rabbi qalban saleeman wa lisanan sadiqan, wa astaghfiruka lima ta‘lamu, wa as’aluka khayra ma ta‘lamu, wa a‘udhu bika min sharri ma ta‘lamu wa ma la na‘lamu, fa innaka ta‘lamu wa la na‘lamu, wa anta ‘Allam al-ghuyub. "O’ Allah (swt), forgive me for what I have sent ahead and what I have delayed, for what I have concealed and what I have revealed, and for my excesses against myself, and for what You know better than I. O’ Allah (swt), You are the First and the Last. There is no god but You. By Your knowledge of the unseen and Your power over creation, if You know that life is better for me, then grant me life, and if You know that death is better for me, then take me unto You. O’ Allah (swt), I ask You for fear of You in secret and in public, for the word of truth in contentment and anger, and for moderation in wealth and poverty. I ask You for unending bliss, for joy that does not cease, and for contentment with what You have decreed and a comfortable life after death. I ask for the sweetness of looking upon Your face and a longing to meet You without a harmful calamity or a dark fitnah. O’ Allah (swt), adorn us with the adornment of faith and make us guides and guided ones. O’ Allah (swt), guide us among those You have guided. I ask You for determination upon the right path, stability in the affair, gratitude for Your blessings, good health, and the ability to fulfil Your rights. O’ Lord (azj), I ask You for a sound heart, a truthful tongue, forgiveness for what You know, the best of what You know, and protection from the evil of what You know and what we do not. Truly, You know and we do not, and You are the Knower of all that is hidden.'"
