Sooraj Hooa Madhaam

I am not sure about the Dm Chord in the following song.
Corrections are welcome

Initial music with some instrument I don't konw :
Gm... F...
Gm... F...
Gm... F...

then with chorous the same thing,
and finally slow strum with voilen as :
Gm...F...Dm...Gm

Gm F Gm F
Sooraj hooa madhaam, Chaand jalnea laga,

Gm F Gm F
Aasman yeah hai,kayoon pighalne laga

and the beats start...

same 2 lines as above.

Gm F Gm

Gm F Gm

F Gm

F Gm

female voice :
Gm F Dm Gm F Gm
