Although I got confused I got a new route. Just reach the rainbow roundabout straight from Hamad Hospital signal . Keeping going straight from that roundabout till you reach the next roundabout and still keep going till you reach one more roundabout and then take an U-turn and keep going on the 3rd lane and within 100 to 200 meters you can see the Malaysian Embassy Flag and building on your right.

Tks for the help elxxxv.
