Many Muslims in the United Kingdom (UK) celebrate Eid al-Fitr. It marks the end of the month-long fast of Ramadan and the start of a feast that lasts up to three days in some countries. This event involves many Muslims waking up early and praying either at an outdoor prayer ground or a mosque. People dress in their finest clothes and adorn their homes with lights and other decorations. Old wrongs are forgiven and money is given to the poor. Special foods are prepared and friends or relatives are invited to share the feast. Gifts and greeting cards are exchanged and children receive presents.  Eid al-Fitr is a joyous occasion but its underlying purpose is to praise God and give thanks to him, according to Islamic belief. On the occasion, Britain’s Foreign Secretary William Hague said:  “I am delighted to send my best wishes to Muslims in Britain and across the world as they mark the end of the month of Ramadan. “Eid ul Fitr celebrates the completion of a month of fasting, prayer, devotion and charitable giving. It is a fitting time to remember all those who are in need around the world, in particular those who are struggling to build a better future for their societies in the Middle East and North Africa.  “So to Muslims around the world on this very important day of celebration, I send my very best and wish you Eid Mubarak.” Eid in the Square has been annually held in London to celebrate Eid al-Fitr, bringing diverse communities, families and friends together in recent years. It features live entertainment, stalls, exhibitions, prayer marquees, and a children’s play area. Some cultural heritage centres may host festivities associated with Eid al-Fitr. Many Muslim communities throughout the UK, including in Scotland, also organize their own festivities for this occasion. Eid al-Fitr is not a bank holiday in the United Kingdom. However, many Islamic businesses and organizations may alter their business hours during this event. There may be some congestion around mosques around this time of the year.
