Millions of Muslims from around the world are preparing to celebrate Eid al-Fitr, the official end of Ramadan, the Islamic holy month of fasting.

Depending on the sighting of the new moon, the occasion known as the 'festival of the breaking of the fast' in Arabic will take place on or around 17 July.

After 30 days of not eating or drinking from sunrise to sundown, as well as refraining from sexual intercourse, smoking and profanity in a bid to become closer to Allah, specific prayers are performed at mosques before families and friends host gatherings and feasts.

Ahead of the big day, IBTImes UK looks at some notable celebrities joining the festivities.

Zayn Malik

Former One Direction star Zayn Malik is Muslim. As a result of being 1/5 of one of the biggest groups in the world, the 22 year old has faced fierce scrutiny and often been forced to defend his lifestyle choices.

He previously spoke about the racist abuse he receives on Twitter, telling the Mirror in an interview: "Nasty things were said like I'm a terrorist. How can you justify that?

"I believe that your religion should be between you and whoever your belief is in."
