Kufr-o-Deen in Iqbal’s couplets
Aql-o-dil-o-nigah ka murshid-e-awwaleen hai ishq
Ishq na ho to shar-o-deen butkada-e-tasavvurat
Ishq na ho to shar-o-deen butkada-e-tasavvurat
Love is the first teacher of intellect, heart and sight. Without love, even law and faith become only a temple of empty ideas.

Ai aab-e-rud-e-Ganga wo din hai yaad tujh ko
Utra tere kinare jab karwan hamara
Utra tere kinare jab karwan hamara
O waters of the river Ganga, do you remember those days — when our caravan first halted upon your banks?
