“The Messenger of Allah (peace and blessings of Allah be upon him) said: ‘There is no one among you who, when he is stricken with distress and grief, says, “Allahumma inni ‘abduka wabnu ‘abdika wabnu amatika naasiyati bi yadika maadin fiyya hukmuka, ‘adlun fiyya qadaa’uka. As’aluka bi kull ismin huwa laka sammayta bihi nafsaka aw allamtahu ahadan min khalqika aw anzaltahu fi kitaabika aw asta’tharta bihi fi ‘ilm il-ghayb ‘indaka an taj’al al-Qur’aana rabee’a qalbi wa noora sadri wa jilaa’a huzni wa dhahaaba hammi [O Allah, I am Your slave, son of Your slave and son of Your maidservant, my forelock is in Your hand. 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 You taught to any of Your creation, or revealed in Your Book, or You have preserved in the knowledge of the Unseen with You, that You nmake the Qur’aan 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 distress and his grief, and will give him joy instead…”
