President Higgins has sent his best wishes to Ireland's 60,000 strong Muslim community as it celebrates the festival of Eid this weekend.
It marks the conclusion of the annual period of prayer and fasting, Ramadan.
In a statement, the President thanked Muslims for transcending the difficulties of Covid-19 during Ramadan and for their contribution to society.
This year, celebrations have been scaled back due to coronavirus.
Dr Nooh al Kaddo of the Islamic Cultural Centre says it is a very strange time for Muslims.
He said: "All the families will gather, but in a very small group, which is very strange for us, very unusual for us.
"It is a very, very difficult and hard time. It's a time for a celebration, so you can just imagine it's a time to enjoy the company of the people, that you cannot do."
