Yes, but this isn't. "Hence, keeping this in mind if one is forced to sign the above in order to become a citizen or the only way of attaining citizenship is by acknowledging the above, then one may sign it with the intention that Shari’ah and Deen will always be his yardstick."
Sharia law is Mohammedan law and is not the same thing as natural law. My understanding is that, under Sharia law, Jews and Christians are treated as dhimmini (second class citizens whose freedom of worship is severely restricted) and members of other religions are treated even worse.
One reason why Israel drives some of them them mad. They believe it is against the will of God that Jews should govern Muslims.
