What I mean is that formally, those laws (Sharia) are not applied selectively. The practice is different, but that's not quite the same thing. Historically, when the concept of rule of law was first introduced, it was to counter the then-prevailing idea that laws officially don't apply to kings, who are above the law. In places like Russia, this was even manifested as part of the title - "autokrator" grew to specifically mean that the ruler is not subject to anyone else's will (including any laws).
