There is no ruling among the rulings on the obligations of the Sharia, its Sunnahs, and its recommendations that does not have a ruling in the inward, or more, to the extent of what is open to the servant regarding that, whether it is an obligation, a Sunnah, or a recommended thing. It is necessary and this is limited to all the other legitimate acts of worship, and in this way the ruling of the outward is distinguished from the inward. The apparent applies to the hidden, and there is no legitimate matter in the hidden that applies to the apparent, rather it is limited to it, for the hidden is all meanings, and the apparent is tangible actions, so it moves from the tangible to the meaning and does not move from the meaning to the sense .
