O Allah, Master (and owner) of the Dominion (or Kingdom), You give the dominion to whom You will, and You take the dominion from whom You will, and You exalt whom You will, and You humiliate whom You will. In Your Hand is all goodness. Verily, You are Able to do all things. The Beneficent and the Merciful of this world and the hereafter, You bestow them on whomever You will and withhold them from whomever You will. Have mercy on me, (such) Mercy that would not make me in need of the mercy of others (than you). The Messenger of Allah (ﷺ) said to Mu'adh (RA), 'If you pray this Dua, Allah will repay you even if you have a mountain of debt.
