Gubare-raah ko le jao aasmano tak
Ye azam-walon ka tohfa hai aasmano ke liye

Gubare-raah – the dust that rises from a street procession
Aasman – metaphorically represents Khuda here
Azam-Walon – Determined people

In trademark Iqbal style of poetry, he calls out to none less than Khuda Himself, almost challenging in his tone, calling out to all the strong-minded and determined people to stand up and unite to change destiny and God’s plans.

Here’s another Persian couplet that shows Iqbal’s poetic genius, where he exhibits the triumph of man over God:
Tu Shab Afridi
Chiragh Afridaam

You created the Night.
I (man) created Light.
