     Islam is one of the three major world-famous religions. Nowadays, about 900 million people in the world believe in Islam according to statistics, accounting for 18.5% of the world&#39;s total population, and they are mainly distributed in North Africa, Western Asia, South Asia, Southeast Asia, etc. Moslems of varying quantities are nearly distributed worldwide except a few countries. At present, people in about 28 countries almost believe in Islam, Moslems in 35 countries account for over 50%, and more than twenty countries among the 63 countries are Arab countries. Islamic etiquette requires five daily worships, one weekly worship (i.e., Sunnah Jumah worship) and two annual festival worships (i.e., worships of Corban Festival and Lesser Bairam). The days from December 8 to 10 of Islamic calendar are statutory hajj dates (i.e., principal hajj). Visiting Mecca Kaaba beyond the dates is referred to as “UMRAH” (i.e., “secondary hajj”). The so-called “hajj” is generally referred to as “principal hajj”. It is compulsory for healthy Moslems having enough money to visit Mecca once in life under the condition of a safe trip.
