Well .. this song is for people who alraedy married (and want to get marry ) .

My first time listening to this song is when my officemate Rustam played this song in his car .. So I wonder what is the meaning when the arabic verse came in .. so I search for the lyrics

You notice there is no translation for the arabic part .. so using google translate I get this

Baraka Allahu Lakuma wa Baraka alikuma
Wa jamaah baina kuma fee khair.
Barakallah hu lakuma wa baraka alikuma
Wa jamaah baina kuma fii khair.

english :

God love Adam
God’s blessings and peace upon the Messenger of Allah
