because of their religion
During fasting in Ramadan, Muslims are not allowed to eat, drink, smoke, or practice sex in the daytime from Dawn to sunset. They are allowed beyond this period to eat, drink, smoke, and practice sex.
Ramadan is the ninth month of the Islamic calender. It is the Islamic month of fasting, in which participating Muslims refrain from eating, drinking and sexual relations from dawn until sunset. During Ramadan, Muslims ask forgiveness for past sins.
Muslims are allowed to eat before dawn, known as suhoor, and break their fast after sunset, known as iftar, during Ramadan. They abstain from food and drink from dawn until sunset as an act of worship and self-discipline.
Muslims wake up an hour or two before dawn and eat. Then they fast until the sun sets. They then break their fast. Contrary to some beliefs, Muslims do not "pig out" all night, then sleep all day. Muslims rest at night just as usual, and may take a nap or two during the day to keep their strength up.
They are not supposed to eat while the sun is up (from dawn until sunset).
In Ramadan, Muslims eat once before dawn and then they fast all day until sunset. After sunset they can break their fast with whatever they want but it is recommended to break fasting with dates and water. Then, Muslims can eat whatever they want as long as it is not haram (not allowed). Refer to the related question below for more information.
No, Muslims are not allowed to swallow saliva intentionally while fasting during Ramadan. The general rule is to avoid ingesting anything, including food, water, or any other substances, from dawn until sunset.
Muslims feel that the food that is available should be food that other Muslims enjoy; as well as oneself. At Ramadan- Muslims feast on ALL of their favorite foods... even foods they were banned to respect during fasting... such as -Pork -Beef -Alcohol Muslims enjoy the Ramadan because it is a time to "pig out" (as one might say)... after Muslims follow their religious path into fasting or starving themselves from Sunrise to Sunset. Water... also counts as a part of fasting that is not allowed.
Ramadan
During Ramadan, Muslims are not allowed to eat, drink, smoke, or engage in sexual activity from dawn (Fajr) until sunset (Maghrib). Additionally, they are encouraged to avoid engaging in negative behaviors or acts such as lying, gossiping, and other forms of misconduct throughout the entire day, not just during fasting hours.
Suhoor and Iftar are important to Muslims, especially during the month of Ramadan. Suhoor is a meal eaten before dawn during Ramadan, when a Muslim is obligated to fast. This meal gives him/her energy so that they will be able to function well the rest of the day. Iftar is the meal after Maghrib prayer when Muslims break their fast by eating a large meal. They thank Allah for the food that they have and they eat after they have fasted the whole day, from dawn to sunset.
Of course you can but not recommended because; during fasting in Ramadan; you are not allowed to practice sex (oral or intercourse sex) with your marriage partner during the fasting period (during daytime from dawn to sunset).
