عيد مبارك / كل عام وأنتم بخير
ʿĪd Mubārak; Kull ʿām wa-antum bi-khayr
“Blessed feast; may you be well every year”: the greeting said at ʿĪd al-Fiṭr, ʿĪd al-Aḍḥā and other annual celebrations.
What it means
ʿĪd Mubārak means “a blessed festival”. Kull ʿām wa-antum bi-khayr means “every year, may you be well”, a wish that the person will see the day again in good health and happiness. Muslims say the two together, or either alone, to family, friends and neighbours on the mornings of ʿĪd al-Fiṭr, which ends Ramadan, and ʿĪd al-Aḍḥā, which falls at the end of the pilgrimage rites. People also use the greeting at weddings, anniversaries and other yearly celebrations. It is a custom of courtesy and goodwill and does not come from a text of the Quran. Many Muslims also add a prayer, such as asking God to accept their fasting or worship.
Often misunderstood as
Non-Muslims sometimes think it is a prayer formula with a fixed ritual setting, while it is an ordinary greeting that anyone may use.
