مبارك
Mubārak
The past participle of baraka: blessed, meaning something that God has given increase and good.
What it means
Mubārak means blessed. It is the participle of the verb bāraka, to bless, and so describes something to which God has given barakah, an increase of good. The Quran uses it of the Quran itself (6:92), of the night in which it was sent down (44:3), of the Sacred House at Mecca (3:96) and of Jesus: “He has made me blessed wherever I am” (19:31). The related noun barakah names that increase, and the verb is used in prayers for others. The word is also a common personal name. In greetings it appears in phrases such as ʿīd mubārak, a blessed festival.
Often misunderstood as
Translating it as “lucky” or “fortunate” misses that the blessing in view comes from God.
