The leader of Islam, Mohammed, made certain claims that he was mentioned in the previous scriptures of the Living God, the Torah, Psalms and Bible.
Isaiah 29:12 is one example of a segment of Biblical Text that Mohammedans have attempted to desperately twist and misread in such a way as to claim it is a fulfillment of these mentioned previous references.
But careful examination of the TEXT and the CONTEXT reveals just how incorrect and weak the attempt is, and therefore how desperate.
