and to worship You well. And I ask You for a sound heart and a truthful tongue, and a beneficial certainty, and a flowing, pleasant provision, and mercy by which I attain the honor of Your nobility in this world and the Hereafter, O Most Merciful of the merciful. Oh Allah, I ask You for well-being, a well-being that is followed by a well-being, healing and sufficient, the well-being of this world and the Hereafter. Oh Allah, I ask You, O my master and patron, to be for me a support and a relied-upon, and a pillar and a trusted one, and a provision and a stored treasure.
