Muslims explored North America at least 300 years before the discovery of the New World by Christopher Columbus, according to many researchers.
Dr. Barry Fell, a noted New Zealand archaeologist and linguist of Harvard University showed detailed existing evidence in his work, "Saga America" that Muslims were not only in the Americas before Columbus arrived, but very active there as well.
Ivan Van Sertima, in his renowned work, "They Came Before Columbus" confirms that there was definitely contact between the ancient and early African people with the Native Americans.
Columbus logged on October 21st, 1492, that he was sailing past Gibara on the coast of Cuba he saw a mosque. He also logged that remnants of other masjids have been found in Cuba, Mexico, Texas and Nevada.
