SO you see what you are saying when you say "mabruk" to your friend in Arabic thinking you are saying in a shorter way, congratulation in Arabic, maashaaAllah. what is even more sad is that those who knows Arabic and its Grammar say this word as well thinking the same and it is the Arabs that teaches it as well maashaaAllah.
and someone i just saw wrote this "mabruk" in this form: ma'bruk - what does this word mean i have no idea, usually ' is used to point that there is ع in the word, but there is NO ع whatsoever in these root letters nor in its derived form.
May Allah grant us beneficial knowledge and righteous actions. i thought i should share this. because i would like everyone to say - Mubaarak to me than to say that they knelt down on me. subhan Allah. 'smile'.
Jazakum Allahu khayran
