The Prophet (peace be upon him) taught a specific dua for anxiety and grief: “Allahumma inni a'udhu bika minal-hammi wal-hazan” — “O Allah, I seek refuge in You from anxiety and grief.” Alongside it, the Qur'an points to the deeper cure: a heart that turns back to Allah.
“Those who have believed and whose hearts are assured by the remembrance of Allah. Unquestionably, by the remembrance of Allah hearts are assured.”— Qur'an 13:28 (Saheeh International)
