of God Most High save one in whom the ordinances of the Sacred Law are preserved. (Jamiʿ karamat al-awliyaʾ)". It is related, moreover, that Malik, one of the founders of the four schools of Sunni law, was a strong proponent of combining the "inward science" ('ilm al-bātin) of mystical knowledge with the "outward science" of jurisprudence. For example, the famous twelfth-century Maliki jurist and judge Qadi Iyad, later venerated as a saint throughout the Iberian Peninsula, narrated a tradition in which a man asked Malik "about something in the inward science," to which Malik replied: "Truly none knows the inward science except those who know the outward science! When he knows the outward science and puts it into practice, God shall open for him the inward science – and that will not take place except by the opening of his heart and its enlightenment." In other similar traditions, it is related that Malik said: "He who practices Sufism (tasawwuf) without learning Sacred Law corrupts his faith (tazandaqa), while he who learns Sacred Law without practicing Sufism corrupts himself (tafassaqa). Only he who combines the two proves true (tahaqqaqa)". The Amman Message, a detailed statement issued by 200 leading Islamic scholars in 2005 in Amman, specifically recognized the validity of Sufism as a part of Islam. This was adopted by the Islamic world's political and temporal leaderships at the Organisation of the Islamic Conference summit at Mecca in December 2005, and by six other international Islamic scholarly assemblies including the International Islamic Fiqh Academy of Jeddah, in July 2006. The definition of Sufism can vary drastically between different traditions (what may be intended is simple tazkiah as opposed to the various manifestations of Sufism around the Islamic world). Traditional Islamic thought and Sufism The literature of Sufism emphasizes highly subjective matters that resist outside observation, such as the subtle states of the heart. Often these resist direct reference or description, with the consequence that the authors of various Sufi treatises took recourse to allegorical language. For instance, much Sufi poetry refers to intoxication, which Islam expressly forbids. This usage of indirect language and the existence of interpretations by people who had no training in Islam or Sufism led to doubts being cast over the validity of Sufism as a part of Islam. Also, some groups emerged that considered themselves above the sharia and discussed Sufism as a method of bypassing the
