“The East and the West belong to God: wherever you turn, there is His Face. God is all-pervading and all-knowing.” (2:115)
“Clearly this verse comes as a response to Jewish lies and false contentions that prayers offered by Muslims facing Jerusalem were worthless and in vain. It is saying that in the final analysis prayer is valid whatever direction a worshipper faces, because God’s face will be there. To specify a particular direction is no more than a matter of discipline. It does not mean that God’s face is found in one direction rather than another. After all, God does not wish to make things difficult for people, nor would He want to take away their reward or devalue it.” (In the Shade of the Qur'an by Sayyid Quṭb)
Amen. (Literally: 'Nothing further need be explained.'). In Islamic theological discourse, it refers to an ancient dispute on the attributes of God (e.g. face, hand, ...etc.), and how different groups interpreted them. The traditionalists chose to accept them as is, 'without how'. The rationalists (e.g. Mu'tazili) chose to interpret them allegorically. The phrase Bi-La Kaifa means "without a how". This term is not used often in modern times, except in theological circles. It is amazing that Frank Herbert would be exposed to this term, and make use of it.
