ПОЖАЛУСТО СРОЧНО НАДО СОСТАВИТЬ 5 ВОПРОСОВ (АЛЬТ ОБЩИЙ С ХВОСТИКОМ И ТД ТОЛЬКО НЕ ДЛИННЫЕ ПРОСТЫЕ ЕСЛИ НЕ СЛОЖНО )Islam is the second most popular religion in the world with over a thou¬sand million followers. Islam began in Arabia and was revealed to humanity by Muhammad (570-632), a holy man born in Mecca, to whom God told many things which are recorded in the Koran, the Holy Book of Islam, translated as "the word of God". Those who follow Islam are called Muslims. They believe that there is only one God called Allah I'aebJ. The Muslim building for worship is called a mosque. Very often mosques have a domed roof with a tall tower called a minaret, from which Muslims are called to prayer. Mosques have bare walls and very little furniture. Muslims take off their shoes before entering the & ЫИ mosque and use prayer mats to kneel on them.
Women do not pray in the same place as men. There is usually a screened off area for them. Muslims pray five times a day (prayer times are fixed by the sun and change daily). They wash themselves before prayer and face the direction of Mecca while praying. If it is financially possible, Muslims are required to travel to Mecca at least once in their lifetime. The main Muslim Festival is Ramadan, the ninth month of the Islamic Lunar calendar. During Ra¬madan all Muslims across the world do not eat during the hours of daylight.
Judaism, which has only about 12 million followers, is around 3500 years old and is the oldest of the world's four great religions. This religion originated in Israel. The founder of Judaism is Abraham who is
regarded as the father of Jewish people. Jews see Abraham as a symbol of trusting and obeying God. Moses is also an important figure of Judaism as he gave the Jews the Torah, the Jewish Holy Book, which contains the laws of God. Moses was the leader of Jews who freed them from slavery in Egypt. Moses protected the Jews from the anger of God and negotiated with
God on their behalf. Jews believe in a single God who created the universe.
Jews worship in synagogues. Men and women usually sit separately. Men are required to cover their heads. In most cases worship takes place in Hebrew. The Jewish spiritual leaders are called rabbis.

The most important day of the week is the Sabbath, which is a day made holy. This day starts at sunset on Friday and continues until sunset on Saturday. During the Sabbath, people do nothing that might be counted as work, they shouldn't even drive or cook.
The main Jewish Festival is Passover (Pesach in Hebrew). Pass¬over is the time when Jewish people remember how they left Egypt. It is a major eight-day festival. Matzah (unleavened bread) is eaten throughout the festival. There is a great spring cleaning in the home before the festival to ensure that no trace of leaven is left in the home during Pesach.
