I’ve read many articles arguing that demonstrations against a Muslim ruler, even one who is a tyrant, are not allowed in Islam! Is that true? Doesn’t make sense to me.
“And those who, when transgression hits them, they vindicate themselves” (42:39)
Does this answer your question?
Interestingly enough, this verse comes immediately after the democracy verse
“…And their affair is by consultation between them” (42:38).
