Translation
I seek refuge in Allāh from Shayṭān, the rejected one. In the Name of Allāh, Most Gracious, Most Merciful O Allāh, send perfect blessings and complete peace, upon our master Muḥammad. By virtue of whom all obstacles are removed, Distress is relieved, Needs are met, Desires are fulfilled and a good end may be achieved, And by virtue of whose noble face clouds may be sent, And [send blessings and peace] upon his Family and Companions, With every movement of the eyes, and every breath, By the number of all things known to You.
