Prayers and Meditations — Paragraph 814
Source (Arabic)
أَيْ رَبِّ وَجَّهْتُ وَجْهِيْ إِلَيْكَ نَوِّرْهُ بِأَنْوَارِ وَجْهِكَ ثُمَّ احْفَظْهُ عَنِ التَّوَجُّهِ إِلَى غَيْرِكَ.
Translation
I have turned my face unto Thee, O my Lord! Illumine it with the light of Thy countenance. Protect it, then, from turning to anyone but Thee.
God testifieth that there is none other God but Him.
