Do muslims really fast? Does Quran requires it? No, They are told to start by overeating the previous night ( till early morning next). This will lead to indigestion the whole next day and they cannot eat till evening when the feast and overeating restarts and they again overeat till next morning. This routine continues for one month. This is feasting, not fasting. If Islam is truthful,you would have fasted non-stop for a month, without overeating every night full. They Fraud on every one.
