Sufis in Yemen used the beverage as an aid to concentration and as a kind of spiritual intoxication when they chanted the name of God. Sufis used it to keep themselves alert during their nighttime devotions. A translation of Al-Jaziri's manuscript traces the spread of coffee from "Arabia Felix" (present-day Yemen) northward to Mecca and Medina, and then to the larger cities of Cairo, Damascus, Baghdad, and Constantinople. By 1414, the plant was known in Mecca, and in the early 1500s was spreading to the Mameluke Sultanate of Egypt and North Africa from the Yemeni port of Mocha. Associated with Sufism, myriad coffee houses grew up in Cairo (Egypt) around the religious University of the Azhar. These coffee houses also opened in Syria, especially in the cosmopolitan city of Aleppo, and then in Istanbul, the capital of the Ottoman Empire, in 1554. In 1511, it was forbidden for its stimulating effect by conservative, orthodox imams at a theological court in Mecca. However, these bans were to be overturned in 1524 by an order of the Ottoman Turkish Sultan Suleiman I, with Grand Mufti Mehmet Ebussuud el-İmadi issuing a "fatwa" allowing the consumption of coffee. In Cairo a similar ban was instituted in 1532, and the coffeehouses and warehouses containing coffee beans were sacked. During the 16th century, it had already reached the rest of the Middle East, the Safavid Empire and the Ottoman Empire. From the Middle East, coffee drinking spread to Italy, then to the rest of Europe, and coffee plants were transported by the Dutch to the East Indies and to the Americas.
