The Holy Prophet (pbuh) had advised the faithfuls to recite the following du'a after every obligatory Salaat to obtain Allah's mercy.
O Allah, let peace and tranquillity prevail over the people buried in the graves! O Allah, let the have-nots get rid of scarcity! O Allah, let the hungry be able to eat their fill! O Allah provide clothes to the mortals in tatters! O Allah, enable all debtors pay back the debts! O Allah, cheer up every heart-broken! O Allah, let every wayfarer return to his home! O Allah set free every detained captive! O Allah let every trouble maker see the right path in the common interest of the Muslims! O Allah make the sick get well! O Allah, fill the yawning gaps of destitution through Thy unlimited resources! O Allah, make better our deteriorating condition with the help of Thy free bounties and benefits! O Allah free us from the burden of debts and poverty! Verily, Thou are able to do all things.
Imam Ja'far bin Muhammad al-Sadiq (a.s.) and Imam Musa bin Ja'far al-Kaazim (a.s.) had advised the faithfuls to recite the following Du'as after every obligatory salaat:
O Allah, give me enough means so that I may go to Thy Holy House for pilgrimage this year and every year till I live in ease and comfort bestowed upon me by Thee; do not deny me these opportunities of visiting the venerable places and calling upon the resting abode of Thy Prophet (Thy blessings be on him and on his children), and in the matter of all the needs of this world and the hereafter continue to do good for me. O Allah, I request you to take a decisive decision regarding my affairs in the night of "Qadr", a decision that cannot be reversed, nor can be changed, which includes me among the pilgrims of the "Sacred House" their dutiful pilgrimage receiving Thy approval, their efforts acknowledged their mistakes forgiven, their sins atoned for; and in the course of it make it possible that I live long in ease and comfort, pay back my debts and settle the money obligations. So be it, O the Lord of the worlds.
The following dua has also been advised by the Imams. It is recommended that this Du'a be recited after every obligatory prayer.
O the High, O the Great, O the Forgiver, O the Merciful, Thou are the Lord of the lords, Thee, and Thou hears and sees everything. This is the month Thou has made great, exalted, distinguished, rendered superior over all other months, and this is the month in which Thou has made fasting obligatory for me, and this is the month of Ramazan in which Thou sent down the Holy Quran, guidance for the mankind, which has clear signs to show the right path and set apart truth from falsehood; and Thou celebrated it with the "Night of Qadr" a night better than a thousand months. So, O the Owner of favours and benefits whom none can oblige, have mercy on me by cutting off my drift towards the hellfire and direct me unto the Paradise, O the Most Merciful.
Du'a Faraj
(Du'a for the reappearance of the Imam of the Time (a.s.)
O Allah, be for Your representative the Hujjat (proof), son of Al-Hasan, Your blessings be on him and his forefathers in this hour and in every hour, a guardian, a protector, a leader, a helper, a proof, and an eye until You make him live on the earth, in obedience (to You), and cause him to live in it for a long time.
