An invocation for anguish
Allaahumma rahmataka ‘arjoo falaa takilnee ‘ilaa nafsee tarfata ‘aynin, wa ‘aslih lee sha’nee kullahu, laa’ilaaha ‘illaa ‘Anta.
O Allah , I hope for Your mercy . Do not leave me to myself even for the blinking of an eye (i.e. a moment) . Correct all of my affairs for me . There is none worthy of worship but You.
