The underlying reasoning in both olive and sesame transactions is a ribawi component contained within one composite countervalue and offered separately on the other side. Determine the embedded quantity, allocate its equal against the same component, and then examine whether excess can correspond to other valuable matter.
Hanafi commentary applies comparable reasoning to nuts and extracted oil, milk and clarified butter, or grapes and juice. Each case still requires its own inquiry into genuine components and credible quantities; the formula is not permission for every imagined mixture.
