The holy day of the week for Muslims is Friday. In the Arabic language, the word for Friday means a special type of prayer. On this day, Muslims are expected to come together to pray at their mosques.
Muslims are expected to pray every day of the week in the family home, but Friday is set aside for communal prayer at the local mosque. All Muslim men are supposed to attend Friday prayers, while doing so is optional for women. Muslim women who do attend are separated from the men during prayer time. Friday prayers are important in the life of any Muslim because it is a time to remember Allah and bring communities together. Wikipedia
