Today marks the Feast of Immaculate Conception, Catholics celebrates the belief in the Immaculate Conception of the Blessed Virgin Mary. It is celebrated on 8 December, nine months before the Nativity of Mary, which is celebrated on 8 September.
From St. Mary's website:
The Blessed Virgin Mary was preserved from the stain of original sin in the first instant of her conception in the womb of her mother. This was a singular privilege and grace of God, granted in view of the merits of Jesus Christ. By her conception is meant not the act or part of her parents in it, nor the formation of her body, nor the conception of Christ later in her own womb; from the moment her soul was created and infused into her body, it was free from original sin and filled with sanctifying grace. Her soul was never stained by original sin, nor by the depraved emotions, passions, and weaknesses consequent on that sin, but created in a state of original sanctity, innocence, and justice. She had at least the graces of the first Eve before the Fall and more. This privilege was befitting the one who was to be mother of the Redeemer.
Even though UAE is a Muslim country, diversity is exercised and respected here including religion. Thus we have 2 Catholic Churches in Dubai, one is in Oud Metha and another in Jebel Ali.
