Here's a funny Q&A on Ramadhan from BBC:
Ramadan, What does this mean?
Ramadan is the 9th month of the Islamic calendar. It's when Muslims all over the world spend 30 days observing fast and bettering themselves in principles of faith.
Observing fast? Is that something to do with running, then?
Oh, what is it then?
Observing fast, or fasting, is when a person abstains (or keeps away) from eating and drinking.
What, you don't eat or drink anything? Don't you get hungry? I know I would.
Yes, that's the idea. We fast for 30 consecutive days during the month of Ramadan.
30 days? No one can go 30 days without food and drink-or can they?
No, that's right, which is why Muslims only fast during daylight hours. Once the fast for each day ends, they are allowed to eat again.
