Ramadan has officially started and Muslims in Glasgow and around the world will be fasting for long-hours for around 29 to 30 days.
It means they cannot eat from sunrise to sunset as they focus on prayer, charity and gratitude. Ramadan is the ninth month in the Islamic calendar and the dates change every year - depending on the sighting of the moon.
It's a month of reflection and getting closer to religion as billions of Muslims, globally, observe the holy month.
