Distinct from the angels there is another order of beings made of fire called jinn (genii.) It is said that they were created thousands of years before Adam came into existence. "We created man of dried clay, of dark loam moulded, and the jinn had been before created of subtle fire." (Sura xv. 26, 27.) They eat, drink, propagate their species and are subject to death, though they generally live many centuries. They dwell chiefly in the Koh-i-Kaf, a chain of mountains supposed to encompass the world:[129] {146} some are believers in Islam; some are infidels, and will be punished. "I will wholly fill hell with jinn and men." (Sura xi. 120.) The Sura called Surat-ul-Jinn (lxxii.) refers to their belief in Islam. The passage is too long to quote. They try to hear[130] what is going on in heaven. "We guard them (_i.e._, men) from every stoned Satan, save such as steal a hearing." (Sura xv. 18.) They were under the power of Solomon and served him. (Sura xxxviii. 36.) An 'Ifrit of the jinn said, "I will bring it thee (Solomon) ere thou risest from thy place: I have power for this and am trusty." (Sura xxvii. 39.) At the last day the jinn also will be questioned. Imam Hanifa doubted whether the jinn who are Muslims will be rewarded. The unbelieving jinn will assuredly be punished. Tradition classifies them in the following order: (1) Jann, (2) Jinn, (3) Shaitan, (4) 'Ifrit, (5) Marid. Many fables have been invented concerning these beings, and though intelligent Muslims may doubt these wonderful accounts, yet a belief in the order of jinn is imperative, at least, as long as there is belief in the Quran. Those who wish to know more of this subject will find a very interesting chapter on it in Lane's Modern Egyptians. 3. THE BOOKS.--Al Berkevi says:-- "It is necessary to believe that the books of God have been sent through the instrumentality of Gabriel, to prophets upon the earth. The books are never sent except to prophets. The Quran was sent to Muhammad portion by portion during a space of 23 years. The Pentateuch came to Moses, the Injil to Jesus, the Zabur to David, and the other books to other prophets. The whole number of the Divine books is 104. The Quran, the last of all, is to be followed till the day of judgment. It can neither be abrogated nor changed. Some laws of the previous books have been abrogated by the Quran and ought not to be followed."
