What is the ruling on saying that it is obligatory to fast twelve days as expiation for someone who fainted during prayer and caused the worshippers to leave to help him?

The statement that it is obligatory for someone who has expelled them from prayer to fast twelve days is false, and no scholar has ever said it. Speaking about Allah without knowledge is one of the greatest prohibitions and most severe sins, and it is the root of polytheism, disbelief, innovations, and misguidance. Whoever says such a thing must fear Allah and refrain from issuing fatwas without knowledge.
