If you learn one dua, learn this one — the Prophet ﷺ said it most often. It asks for everything in a single breath: good in this life, good in the next, and protection from the Fire.
“Our Lord, give us in this world [that which is] good and in the Hereafter [that which is] good and protect us from the punishment of the Fire.”— 2:201 (Saheeh International)
