Ramadan .
Ramadan is the month of fasting from sunrise to sunset. This means when they fast that they do not consume any food or beverages from sunrise to sunset. On this month they focus on cleansing the soul and refocusing on God more than originally do. It is not about just fasting, they are just re-evaluating their life and focus more on the religion. It is a month where they get close with family and friends and throw away all the bad things and habits. It is cleaning their lives and strengthens them. Muslims call fasting "Sawm" which means "to refrain" but not to only food or drinks but to the evil actions and thoughts. It is a month of being extremely religious and holy. You may not commit any sins. It is important to give charity on this month and help those in need.
