Supermarkets including Tesco and Asda have launched a range of deals and offers to coincide with Ramadan.
Ramadan is the ninth month of the Islamic calendar.
During the month of Ramadan, Muslims won't eat or drink during the hours of daylight.
Instead, it is common to have one meal just before dawn called the Sahoor meal and another directly after sunset called the Iftar meal.
The end of Ramadan is marked by "Eid-ul-Fitr" - the Festival of the Breaking of the Fast.
