Question:
Is it correct what the Saudis do, shutting down all shops when adhan is called?
Answer:
Forcing people to close shop for salat is an innovation of misguidance in that it gives all prayers the status of Jumua and thereby cancels the special status of Jumua, which is the only time when trade becomes haram from the beginning of adhan to the end of Salat.
