Does placing a small pin in the izar during the stay in Muzdalifah, out of fear of it uncovering, necessitate a fidyah?

Pinning the izar with a single pin is permissible, and no fidyah is required for it, because it is not considered "stitched garments" (al-makheet) which are forbidden by scholarly consensus, as long as the pins are spaced out. Jurists have prohibited pinning the izar if the pins are close together, because then it becomes like a stitched garment.
