The Messenger of Allah (ﷺ) said: “There is no slave who, when he is stricken by anxiety and sorrow, says 'O Allah, I am Your slave and the son of Your male slave and the son of Your female slave. My forelock is in Your hand (i.e., You have complete mastery over me), Your command over me is forever executed, and Your decree over me is just. I ask You by every name belonging to You which You named Yourself with, or revealed in Your Book, or You taught to any of Your creation, or You have preserved in the knowledge of the Unseen with You, that You make the Qur'an the life of my heart and the light of my breast, and a departure for my sorrow and a release for my anxiety' - but Allah will remove his anxiety and replace his sorrow with joy.” The people said: O Messenger of Allah, we should learn these words. He said: “The one hears them should learn them.”
