"I have turned my face unto Thee, O my Lord!"

"Whoso wisheth to pray, let him wash his hands, and while he washeth, let him say:

 Strengthen my hand, O my God, that it may take hold of Thy Book with such steadfastness that the hosts of the world shall have no power over it. Guard it, then, from meddling with whatsoever doth not belong unto it. Thou art, verily, the Almighty, the Most Powerful.

And while washing his face, let him say:

I have turned my face unto Thee, O my Lord! Illumine it with the light of Thy countenance. Protect it, then, from turning to any one but Thee." ...
