Tal'aa albadr - طلع البدر - full moon came up

I would like to invite you to listen to this fabulous lyric and video clip.

Did you listen to the repetitive phrase  " tala'a Albadr "  which is actually the title of the lyrics.

طلع البدر

Full moon came up

full moon is in Arabic :  بدر

Then we add  the definite  :  ال

exactly as adding     :   THE

so it is :            البدر
