When sad or anxious

Allahumma inni 'abduka, ibnu 'abdika, ibnu amatika, nasiyati biyadika, madin fiyya hukmuka, 'adlun fiyya qadauka. As'aluka bi-kulli ismin huwa laka, sammayta bihi nafsaka, aw anzaltahu fi kitabika, aw 'allamtahu ahadan min khalqika, aw ista'tharta bihi fi 'ilmil-ghaybi 'indaka, an taj'al al-qur'ana rabi'a qalbi, wa nura sadri, wa jila'a huzni, wa dhahaba hammi.

O Allah, I am Your servant, son of Your servant, son of Your maidservant. My forehead is in Your hand. Your judgement upon me is assured, and Your decree concerning me is just. I ask You by every name belonging to You with which You have named Yourself, revealed in Your Book, taught any of Your creation, or kept hidden with Yourself in the knowledge of the unseen — make the Quran the springtime of my heart, the light of my chest, the remover of my sorrow, and the reliever of my distress.
