Shapirism

Shapirism or Shabiriyyah is a school of Islamic philosophy and jurisprudence developed by Musa ibn Shabir, commonly known as bin Shapir, on Sydona in the early 10th century. The central feature of Shapiri thought is the complementary synthesis of "fact," embodied in the shahada, and "logic," or reason, as developed by the Istroyan philosophers of antiquity.
