Islam is a word coming from Salam wish is Peace or Peaceful.
Ramadan just finished today, its between 29-30 days month, and people fast because GOD "Allah" wanted rich people to know how it feel to be without food the whole day and working and doing everything normal.
you fast between ALFajer Prayer till ALMaghrib Prayer, from sun rise till sun sit, you don't eat nor drink, isn't the only thing, it tells people to control their emotions, you can't say a bad thing, do anything wrong, its a holy month comes every year.
it meant to be a teaching of self controlling and having the luxury of life behind you, most of us FAST during the day when it summer and hot like hell. being a footballer or anything else doesn't matter Islam isn't a religion that force, GOD gave reasons for people to make up for days they can't fast because of illness, traveling, having to work in a kind of job that needs more force and power, and you can make up for that day any time of the year between the 2 Ramadan month.
some of the guys should easily read about Islam and its teaching, don't stand to what the media say and talk about, try to over come bullshit comes out of FOX news and the likes, and try googleing something and the key words would be
"Islam, Ramadan, Fasting in Islam" it could help if you try to search to English websites made by Muslim people.
hope this offers something to the one who asked.
Eid Mubarak to all
