Dr Iqbal said nicely
Fard Qaim Rabt-e-Millat say hai, tanha kuch nahi
Moj hai darya main, aur berun-e-darya kuch nahi
Qaim = to survive, Rabt-e-Millat = Unity of a nation, Moj hai darya main aur berun-e-darya kuch nahi ( giving example of a wave which can’t survive out of ocean. Similarly, individual is strong as long as he is part of a nation. Together we stand, divided we fall)
Millat kay saath rabta-e-ustawar rakh
Paiwasta reh shajar say, umeed-e-bahar rakh
