Kaleje par patthar rakhna in Iqbal’s couplets
Mazhab nahin sikhata aapas mein bair rakhna

Patthar ki mooraton mein samjha hai tu Khuda hai
Khaak-e-watan ka mujh ko har zarra devta hai
Khaak-e-watan ka mujh ko har zarra devta hai
You have imagined that God dwells within stone idols — for me, every single speck of my homeland's dust is itself a deity.
