Should one reproach those who say "mabrouk" when offering congratulations, based on the argument that the word is derived from "barak" (to kneel/crouch) and not from "barak" (to bless), even though those who use it intend the meaning of blessing?

"Mubarak" is the linguistically and Islamically correct term, as the passive participle of the verb "baraka" (to bless) is "mubarak." This term has been mentioned in the Holy Qur'an and the Prophetic Sunnah. Nevertheless, there is no harm in using the word "mabrouk" when congratulating and supplicating for blessings, as long as people have become accustomed to it. The intention is to pray for blessings, and this is not among the divinely ordained (tawqifi) terms.
