Anwar `Abdullah points out in his book, Khasa'is Wa Sifat Al-Mujtama` Al-Wahhabi As-Sa`udi (published in Paris as no publisher would dare publish in the Arab world), that House of Saud has since 1931 always appointed a blind Wahhabi as a Grand Mufti. So if you are not blind, and get offered the position of Grand Mufti of Saudi Arabia, don't accept. Just run away.
