“Allah does not afflict a slave with grief nor sadness, except that if the slave says:
O Allah indeed I am Your servant, and the son of Your servant, and the son of Your female servant, my forelock is in Your Hand, Your command over me is forever executed and Your decree over me is just. I ask of You with all Your names, which belong to You, which You have named Yourself with, or which You have taught someone from Your creation or revealed it in Your Book or that which You have taken unto Your self with the knowledge of the unseen with You, that You make the Qur’an the life of my heart and light of my breast and keep away from me my sadness, and that my grief goes away-
then Allah takes away his grief and sadness and replaces it with happiness.”
The narrator said: It was said: O Messenger of Allah should we not learn it?
He answered: Of course, it is necessary for the one who hears it, that he learns it.
(Silsilah Saheehah, Al-Albaani)
