Ramadan is the ninth month in the Islamic lunar calendar.
Ramadan is a month where Allah forgives, blesses and rewards Muslims without a limit.
Healthy adult Muslims fast during the month of Ramadan from dawn until dusk. Therefore this includes abstaining from drinking, eating, immoral acts and anger. Other acts of worship such as prayer, reading the Qu’ran and charity are also encouraged during the holy month.
Eid al-Fitr, the Muslim celebration officially marks the end of Ramadan. The exact timing is based on the sighting of the moon. Eid al-Fitr officially begins at the start of the Islamic month of Shawwal.
If you’ve missed any fasts out of necessity and will never be able to fast to make up the lost days afterwards, you’re required to pay Fidya (Fidyah). For any other missed fasts you will need to make them up. For any fasts broken deliberately without need in the Hanafi Madhab you would need to make up the fast and also pay Kkaffarah. In the Hanbali and Shafi Madhabs you would need to make up the fast and only pay Kaffarah if it was broken by marital relations.
