Dua'a For Distress and Grief (Taken from USC-MSA website)

This is based on the following saheeh hadith reported by Imaam Ahmed (Translation adapted from www.islan-qa.com; see question 1392)

The Messanger of Allah (peace and blessing be upon him) said: "There is nobody who is afflicted with distress or grief and who says: "Allahumma inni a'abduka ibn a'bdika ibn amatika, naasiyati bi yadika maadin fiyya hukmuka 'adlun fiyya qadaa'uka, as'aluka bi kulli ismin huwa laka sammayta bihi nafsaka aw a'alamtahu ahadan min khalqika aw anzaltahu fee kitabika aw asta'tharta bihi fee i'lm al ghaybi i'ndak an taja'al al Quraana rabee'a qalbi wa noora sadri wa jilaa'a huzni wa thahaaba hammi"

O Allah! I am Your slave, the son of Your slave, the son of Your maidservant, my forelock is in Your Hand, Your command over me is ever executed and Your decree over me is just. I as You by every name belonging to You, which You have named Yourself with, or which You have revealed in Your Book, or which You have taught to any of Your creation, or which You have perserved in the knowledge of the unseen with You, that You make the Quraan the life of my heart and the light of my chest, and a departure for my sorrow and a release for my anxiety,"- but Allah will take away his distress and grief, and replace it with ease." He was asked,: O Messanger of Allah, should we not learn it?" He said, "Of course, whoever hears it should learn it."
