A Prayer for the Safety of Imam al-Mahdi (A.S.)

In the Name of God, the Beneficent, the Merciful

O Allah! Protect Your vicegerent Hujjat (the Proof) b. al-Hasan and send salutations upon him, and his ancestors, now as well as at all the times, (as our) Imam, Guardian, Supporter, and Guide until such time when you bestow upon him the honor of heading the (Divine) Government. And let the people be delighted in his reign, by bestowing success, and by extending his reign.
